Python doesn't increment like that.

Why don't you write it out for the dude. This write up might end up confusing him the more.

Really? Are you sure of what you just typed? Here is proof that it works.

I don't want to provide all the answers so that our friend can work, learn, and understand.

Please pardon my diction. �
I started coding not too long ago, like 4 months ago. I'm relatively done with HTML and CSS. But JavaScript which most probably is the next stage isn't that easy. Looks so much different and foreign.

Please what job or project can one do with JavaScript, so that I would weigh my chances and see if it's worth the Brain cracking or suffering rather.

If you intend to go far in web development you will need Javascript. Javascript is an important member of the trifecta of web development.
- HTML is for structure
- CSS is for styling
- Javascript is for behavior

Hello, can someone help gimme the guidelines on coding number 1, 2 , 3 and 4
I've successfully done number 5.
Thanks

For question 1, you are simply printing the same value four (4) times. The characters (*) can be stored in a string, after which you can the print.
E.g. my_string = '*******************'
Print my_string the required number of times.

For question 2, you are printing two (2) different patterns, which can be stored in two (2) different strings.
Example
pattern1 = '*******************'
pattern2 = '* *'
You should know what to do from here.

Question 3 is slightly different. There is a clear pattern here, each new line has a new character added at the end of the string. You can simply use string concatenation (+).
Example
custom_string = '*'
print(custom_string)
custom_string = custom_string + '*' # or custom_string += '*'
print(custom_string)

....you know the rest.

Thanks.

After much learning and practises, I came across Functions in python. And I decided to use it to solve the number (4).
And it gave me two answers different from the answer proposed

Please I need to be cleared on this

Hi there, my good friend. Glad to see you are making progress.
For question number 4, I think you misread the question.
1. You see that dot between 47 and 48? It is actually a multiplication operator, not a decimal point. It is placed at a height that is mid height of the two numbers, rather than being placed on the baseline e.g. 47*48 not 47.48 I will apportion some blame to the authors though.
2. We can prove this by manually performing the calculation:
(512 - 282) / (47*48 + 5) = 230/(2256 + 5) = 230/2261 = 0.101724900 = 0.1017 (to 4 decimal places)
Let me just drop a piece of advice which will help you going forward. When you have a problem you are trying to use an algorithm to solve;
understand the problem perfectly, solve it manually to confirm that you know the expected solution. In programing, when programs are tested - you provide known inputs, then you check that the program produces the expected output.
3. You don't need a function or integer division to solve this problem.
4. I also noticed you had some issues with parentheses. In Mathematics there is BODMAS (Brackets Of Division Multiplication Addition and Subtraction) to determine precedence of operations, but in programing we have PEDMAS (Parentheses Exponentiation Division Multiplication Addition Subtraction). To force a certain precedence use parentheses.

//Sample program
result = (512 - 282) / ((47 * 48) + 5)
print(f"The result of the calculation is: {result}" )

Don't give up, you are on the right track.

Is it possible for me to create a mobile app with HTML/CSS &/JAVASCRIPT? That will work offline without the use of internet.

Yes you can.

You can access that with JavaScript nowadays

PWAs have access to some, not all.

Karleb:


I appreciate your contributions as it opened my eyes to a lot about mobile application development.

Even though Kotlin is better than Java at mobile application development, it's birth is as result of the dispute between Oracle and Google about some sort of license issue, I guess.

You should see that I'm more focused on the jobs, especially as a Nigerian. Flutter became a thing in 2017, React native is older. It has more jobs.

Unless you are required to learn Flutter in a company, I believe a developer best bet at mobile application development should be React Native.

As per Javascript, it's a language we all hate to love.

You are right, I forgot about that nonsense Oracle did recently.

Nigeria will always remain in a poor state until we split.
In my community, a man always beats his wife blue black. When his brothers, both younger and older were tired of his stupidity, they all came down to the village, it wasn't even on a festive season. They tied him up, hands and leg! This unrepentant wife beater was converted that day to a loving husband. They did not beat him! All they did was lift him up, allow him fall on gravity! He was screaming on top of this voice, the wife couldn't bear it. They chase her way. After they finished dealing with him, they all dressed up and returned to their various location. Till today, that man has never touched that woman. In fact, the woman said she never knew such amount of love was in her husband!
If it was the woman's brothers that did that, it would have caused more problems for the woman. Probably these same brothers of him will call for heads.
This is the state of Nigeria! When someone commits crime, he cannot be punished or even called out because of tribal sentiment!
The last protest died a natural death because of tribalism. EFCC hardly convict anybody because of tribalism. Every level of incompetence in different government agencies is because of tribalism.
If everyone are to be on their own, standard will improve greatly. Today we have a sharia judge as Chief Justice of the nation! Someone who can't interprete the simplest of law! Someone who never went to a law school! That's what tribalism does.
The painful part is the same lazy soldiers and police officers we are seeking a better Nigeria for became our enemies.
In fact, Nigeria will never ever work. One thing I am certain of is: if we go our separate ways, things will be done by merit down south. Even this same north will come to hire you for the same merit they have rubbished for decades!

You sir, are very wise. This is one of the most insightful things I have read on this site. Another reason Nigeria will probably never be great is because Nigeria is built on a foundation of innocent blood, the blood of the slain cry out to God daily for vengeance.

PHP is dead yet it still food on our table, PHP still funds our account, Abeg dead man putting money for person akkant died. I have been doing PHP for almost 10years, Abeg

I think PHP is the bogeyman, the man that refused to die. Just like Benjamin Button, PHP keeps getting fresher and better with each release. I am sure when some Node developers sleep they always have PHP based nightmares . PHP is not going anywhere anytime soon.

Karleb:
Personally, I think it is shiny object syndrome.

Everyone wanna learn the latest tech.

I don't know about Ionic but React Native has been around before Flutter, it definitely has more jobs than Flutter.

I disagree with your assertion that Flutter adopters are suffering from shiny object syndrome. Progress shouldn't be abandoned because there is a solution already. Consider Kotlin, it was developed to address some of the shortcomings in Java (like the infamous NullPointerException), it is a nice drop in replacement for Java - which many developers are thankful for.
Now when it comes to Flutter, what can we say about the alternatives.
1. Xamarin - cool solution, but has driven many a developer to the brink of madness, because of the way it forces you to do certain things - the .NET way.
2. React Native and NativeScript - excellent options, but some people aren't comfortable with JavaScript. Also things can get complicated in certain scenarios.

Flutter also has its own issues, also there is that latent fear that Google can stop developing it. As the popular saying goes "...different strokes for different folks...", use whatever (proper tool) you are most comfortable with.

NobleEugene5:
I've been learning ionic development for somedays now. But wherever I go, I see Nigerian programmers developing their apps in flutter. So my esteemed nairaland programmers, please tell me what you enjoy the most about flutter .

Warning, long answer ahead.

To know why people use Flutter, let's get the big picture. There are presently four ways to create mobile apps - Android and iOS apps.
1. Progressive Web App: this is simply a responsive web app developed with HTML/CSS/JavaScript. There is no need for installation, but they don't have access to the phone's native features (APIs - Bluetooth, vibration, battery, gestures, etc).
2. Hybrid apps: Cordova, Ionic, and Phonegap fall into this category. These solutions also use HTML/CSS/JavaScript. They use a native wrapper to envelope your code, thereby providing access to native APIs, but they are not as fast or optimised as true native apps.
3. Native apps: with these you create apps with the native toolset (SDKs) and languages meant for such platforms. These apps have access to the entire mobile API (Android or iOS), are fast, and are highly optimised for their platforms. For Android native we have Java/Kotlin (Programming language) with Android Studio (IDE), while iOS uses Swift (Programming language) with XCode (IDE).
4. Cross platform native apps: here we have React Native (uses a form of Javascript - JSX, from Facebook), Flutter (uses Dart, from Google), Nativescript (uses Angular, Vue.js, TypeScript, or JavaScript) , and Xamarin (uses C#, from Microsoft). These solutions produce native apps with full access to the underlying APIs. They enable you to write your app once and simply use the same codebase for other platforms, saving you time and money. You don't need to hire Java/Kotlin and Swift developers to create separate apps.

As to why Flutter is popular - it is newer than the other cross platform options, most of the frustrations and short comings encountered in other solutions have been ironed out in Flutter. Also Flutter (and Dart) is very easy to develop in. Part of the popularity of React Native and NativeScript stems from the fact that JavaScript developers have a very low barrier of entry. Is Flutter better than React Native, NativeScript, and Xamarin? That is subjective, it depends. But when it comes to PWAs and hybrid apps - I will choose Flutter over those two every single time.

I hope I have not bored you, thanks.

Bro, I do see you on various tech/programming thread contributing, making lots of beautiful submission, giving advice etc.

I wanted to quote you in ''Chronicle Of A Data Scientist/analyst'' thread but it was difficult finding your moniker because of the number of pages. I never taught I could see you on this thread.

I want you to put me through, I sometime learn the basics of php late last year but I dropped it because on YouTube, I never saw any complete tutorials project on creating a website, from start to finish. The ones I was, halfway, they direct one to buy there complete course which I am financially handicap.

Bro can you send/give me the tutorial you used in learning php/WordPress with practicals, from beginning to end or if there is a YouTube channel you can point me to

I will so much appreciate it.

You have to dig to find the good stuff. Try searching for the following books - "PHP The Right Way", Learning" PHP 7", and "Learn PHP 7". Remember, nothing good comes easy.

tensazangetsu20:
I started this thread because of the other thread a nairalander made about monetizing his skills.

Most people who learn programming start this way. HTML, CSS, JavaScript, React or angular or Vue and Node or python and Django. This are all great technologies but there aren't any easy to make money with. Getting a job with the MERN stack nowadays isn't easy. Node only powers 0.9 percent of websites globally and yet everyone wants to learn it. Hng internship everyone wanted Nodejs. 90 percent of the tech industry still uses relational and MySQL databases yet people are killing themselves over nosql databases like MongoDB and of recently graphql.

If you look on the freelance market, Upwork, Fiverr, freelancer et al and also look at the general job market you would see that there aren't that many opportunities for those stacks. The thing that gives people money, the things a junior developer can start to use to put money in their pocket isn't taught. Go and look up WordPress plugin development from youtube and there's just like two videos that explain the process. If you really want to get deeper into that, get ready to read your eyes out on the WordPress documentation. It's also the same thing with WordPress theme development. Magento is also another hot area. The largest E commerce platform in the world yet it's not taught anywhere. Shopify isn't also taught anywhere. Shopify uses liquid as its own programming language base. When was the last time you heard about this or saw anyone teaching or using it. Even the resources to learn these stuffs are very scanty.

I am presently working on a Shopify website and instead of coding a review page, I recommended to the client that we buy an app that does the same thing from the Shopify store. Would you believe a Shopify app which is basically just a JavaScript touch carousel that displays your reviews on your home page has 5 dollar monthly subscription with more than 10000 users. The theme the client is using. I had to rewrite most of the CSS. He bought it for 200 USD. I wonder how the theme was even accepted on Shopify. I mean this guys are banking low key and this are technologies no one talks about or even looks at. Everyone is MERN stack, MERN stack. If you mention WordPress they fit kill you or remove your head. Why does the tech industry hide where people can make money from men?

I actually align with @plat0 here. The main thing I always remember is - solve people's problems, while using the best tools available at your disposal. Businesses do not care about your tech stack, they care about results.
For example, PHP was built for the web - so it excels there. I would be crazy trying to create a CLI app, or worse yet a desktop GUI app with PHP - it is possible, but not worth it. If I want to dabble into data science - Python would be my go to. Every tech stack has its own niche where it will excel.

MrJavaS:



You are right bro. But even though there's a 95% chance of failure one needs to try. That others tried and failed doesn't mean one should give up.

Hanging on to obsolete technology isn't the way. The MERN or MEVN is overtaking the likes of WordPress and PHP. It'll take time though. Unless one is only after the money. It's no use devoting time to learning the likes of PHP or WordPress (You're not even considered a developer sef)

PHP outdated? Don't make me laugh. You are probably referring to old versions of PHP (3, 4, and 5). PHP7 is lit, PHP8 will also be dropping this year. If you tell me PHP was crap before - no problem, if you tell me PHP made it easy to write unsafe code before - I would agree with you, but calling PHP outdated - no way, that is a declaration of war.

syluck:
So I tried practising on users input after much concatenations and formatting.

From your screenshot, there are indentation errors on the last two lines of your program. The 'else' should be on the same level of indentation as the previous 'elif'. You can even notice the 'else' is underlined with a red squiggly line to point out the error.

syluck:


If I'm not mistaken, what you are portraying is simply this:

Python variable helps point out those values stored in its memory not that it holds those values?

If it' doesn't hold those values, please I may be tempted to ask what then hold those values in python programming language?

Hi, sorry for the late reply. I got banned by the anti spam bot for posting my earlier reply.
Remember, you are on a computer. All the values that are used in a program are stored in the computer's memory. This is a general concept, and it is not specific or exclusive to the Python programming language.
When you create a program, all the values you use in your program are stored in memory, but to make it easy to reference or call such values you label them - with a variable. You can then get these values by using variables - which point to where the actual value is stored.
What I am explaining is a form of abstraction, it is a way of hiding complex things using simple concepts. Without this type of abstraction you will have to know about memory, memory locations, and memory addressing when writing your programs. The reason I pointed this out is because it will help you later in your programming journey, better to understand it now than later.

syluck:
I did learnt a lot yesterday, would have loved to upload some pictures but I think I will chop ban again . Cos I uploaded some command line workings on my pc, I was banned for a day and the post got deleted.

Over to today. Learning variables and strings in python
-understanding how to assign and learn.
-learning python variable.

Well, a python variable is used to hold a value.

x = 10
Days in a week = 7

The X and Days... is a python variable holding the values, 10 and 7 which is 17.

Hi, glad to see you are getting good mileage on your journey. Not trying to come across as snobbish, but I just want to correct an impression you have.
Variables are not containers, a variable is more like a label that points to a value. Values (integers, floats, boolean, strings) are stored in memory, so a variable points to a memory location. Don't just take my word for it, here is proof. There is a function in Python called identity - id(). id() is used to return the memory location of a particular value.

Exercise
Create two or more different variables, then assign the same value to each variable.

my_var = 34
another_var = 34
third_one = 34

print(id(my_var))
print(id(another_var))
print(id(third_one))

The value returned should be the same for the three print functions. The actual value will also depend on the particular system you run the code on.
Hope I have not confused you though, because this concept is very important.

I had the same laptop , it was a beast, I use that thing play pc games till one idiot broke my laptop.

Mine was stolen, at gun point. I played a lot of games on that laptop, I still have fond memories of that laptop.

Serious pcsx2 and radeon worked well for you, AMD always had bad experience with emulators

Yes, if I remember correctly it was a Radeon HD7870M GPU, that thing was a beast then.

Hey there
Thank alot for clearing this up
I've been saving to buy a phone but I've been confused by most of the specs mostly the 'chips'
I keep seeing things like 'snapdragon'
What do these mean, and what are the best chips?

Snapdragon is a brand of SoCs developed by Qualcomm. Others are the Helio and the Dimensity series from Mediatek, Kirin from Hisilicon (Huawei), Exynos from Samsung, and the Bionic series from Apple.
Each manufacturer has different classes of SoCs (except Apple who only produce flagship SoCs) - entry level, budget, midrange, and flagship.

Thank you bro and God bless you.
So there's no how I can play any ps2 games on this laptop at least even if it's to manage

You can, but you will hate the experience. To put it in perspective, I currently have a laptop with a 2nd generation Core i5 CPU, 6GB of RAM, and Intel HD3000 graphics - my laptop struggles terribly with PS2 emulation, it is not powerful enough. Funny enough, I once had a laptop with a 4th generation Core i5 CPU, 4GB of RAM, and an AMD Radeon 7870 GPU that emulated PS2 games with ease.

AIlahuAkbar:
yeah it's a 2008 model laptop
can you view this one below?

Yes, it is clearer. Unfortunately, that laptop is seriously underpowered.

- 2GB RAM is not good enough for any type of high end gaming or emulation.
- Core 2 Duo is an outdated CPU.
- Your GPU is also outdated.

You will be needing another laptop for high end gaming and PS2 emulation.

I need ps2 games like mortal Kombat Shaolin monks and pes.
your opinion pls

It seems your system has a Core 2 Duo CPU, which is ancient by today's standards. If indeed it has a Core 2 Duo CPU, heavy gaming and even PS2 emulation will be difficult.

Please how do you divide in Python to get an even number or odd number without using modulus

Hi. Division is repeated subtraction, so if you repeatedly subtract two (2) from a number until you get either one (1) or zero (0) - you will get what you are looking for.
Example 1: Seven (7)
7 - 2 = 5,
5 - 2 = 3,
3 - 2 = 1
Since we got one and not zero, it means 7 is odd.

Example 2: Ten (10)
10 - 2 = 8,
8 - 2 = 6,
6 - 2 = 4,
4 - 2 = 2,
2 - 2 = 0
Since we got zero and not one, ten is even.

In fit of pride, hope @Omotolsy won't destroy that reputation he is trying to protect according to Nymphomaniac ''the esquire'' ......


age when you have this kind of demeanor.. business is not for everyone, especially people with big ego ...

AM not on any side by the way....that was a neutral observation .....ADIOS

Oh, wow. Can you see how you just contradicted yourself? You are accusing the seller of having "a fit of pride", and then you go on to type " business is not for everyone, especially people with big ego", and finally to top it off claim you are making "a neutral observation".
Since your are proud of what you typed, my prayer for you is this - in your time of need, may you be judged exactly the way you have judged the seller.

Hello Everyone.

I reached out to Dragnet and Seun on this matter.
People also reached out to Dragnet and calling his name that this thread be pulled down but its fine the thread can stay on.

They have decided to do nothing about such a very impossible claim which is obvious to all to see.

This guy is still going about my threads and writing evil reports. He claimed i intentionally sold him a cracked laptop and started swearing up and down wishing himself evil.

The same guy is now saying i manipulated the videos i sent to him lol. That means i manipulated him for 2 months without he noticing a cracked screen lol.

Please see a screenshot shot of what he wrote on my thread few minutes ago.

Hi. I want to commend you for your maturity in handling this badly scripted smear campaign. I just want to say something which might sound a little bit controversial.
Whenever a prospective customer starts begging excessively, lamenting they don't have enough money, asking very annoying questions, or asking you to make weird concessions - avoid them, or make them sign an agreement. From my investigations, some of the most vicious and ungrateful customers are usually those you made some personal concessions for.
