I'm just glad I'm improving day by day

naijasensei:
Why are you using the eval function in your code?

According to the pdf I'm using to work on, it has eval throughout. I kinda decided to use it though

I’ll like to learn programming and graphic designing.

I have a budget of 100k what is the best laptop I can get for that price?

Hmmmm I think the amount is too much o.(well, maybe you're going for a brand new one)

If you intend getting a window pc, just buy one that the window starts from 8.1. why this? Because most programming languages app uses the latest window version. For instance, the latest python programming language app on a pc accepts window from 8.1 version. Secondly, check the RAM, ROM etc.

Came across this and I tried running the code.

Number 2 and 3 precisely. I'm having problem on both.

In Number 2, I ran the code according to the best of my knowledge but the only issue is having both the Fahrenheit and celcius on both (uppercase, lowercase, first letters both capital and small)

Then for number 3, I just need to understand how to implement the -273.15 when coding.

Thanks

Dear programmer,

I just got myself a HP ProBook laptop and I can say I am very much ready to begin my programming journey. Now my humble questions please:
1. What online platform can I get quality beginners lectures free for my coding adventure?
2. What softwares do you recommend for this purpose, especially an interpreter software?
3. Any other advice dear pros for a beginner like me?

Thank you

Hey bro, I'm on the same part with you. I've been learning programming for quite some time. Nov 24 will make it a month I've been on Programming. Guess what? I'm improving day by day!
Before I went into learning Programming, I found out that there are various programming language, like java, c#, Python etc. From reviews I saw and read from various sources, I came to conclusion that I should start with python programming language. Moreover, there's this video tutorial about python programming language I came across here on Nairaland. It made me become too enthusiastic about python. But before this, I have this dream of creating a website which I can't disclose for now. I'll advise you, you really need to hold on a dream in order for you to last long learning Programming. What's that special thing that made you want to be a programmer? If you have an answer to this question, it will keep driving you to learn everyday.
I won't lie, it is not easy. Programming is very versatile and wide, it somehow gets complicated but with consistency, you'll overcome the stumbling blocks. So far, I've been able to run some codes on my own even after much practises.
Bro, I'll advise you to take ur time and watch that video tutorial. Start from the beginning, follow whatever he's doing there, let your pc be there with you. I'll drop the link below.
In order not to confuse yourself, make sure you have gone through all the videos and have done some practises, then you can go for pdfs or python apps.
Currently, I'm reading a concised pdf about python and using a tutorial python app(not python app itself, though I still have the python app) to learn and run some codes.

At first everything will be strange, confusing and frustrating. But don't give up. I created a thread here on Nairaland and I've dropped some questions when I got confused, we have programmers experts here ready to help a newbie, you can create yours as well. Don't pay anyone a dime to learn programming, atleast I didn't.
Like I said, Programming is a complex world on its own.
Lemme burst ur head a little, Programming is mathematics, but this time around not a boring one you'll need to just write on paper. Programming is a mathematics that you'll write and then get to see it create something spectacular and solving problem u can never think of. This will excite you I swear. Excitement comes in more again when you've successful ran some codes on your own after much practice.

Bro, start with python. It's very easy compared to what I've been hearing about java, c# etc. (Though I will eventually learn java after python)

Programmers like naijasensei, bovage, semtu, karleb, and etinosa1234 here on Nairaland has helped me tremendously. You can always call on them if you're stuck for more clarification.

Bon voyage as u start this beautiful quest.

naijasensei:
No shame in that. Some of the concepts are a bit abstract, so it might take a while to understand. Whenever you get stuck, just take your time, relax, do something else, then return to the problem.

Okay.

naijasensei:
Question 9 is about a sequence referred to as the fibonacci sequence. It begins with two numbers: 1, 1. Subsequent numbers in the sequence are gotten by adding the two previous numbers together. For example, the third number is: 1 + 1 = 2. The fourth number is: 1 + 2 = 3. The fifth number is 2 + 3 = 5, and so on. Your program should request for the user to input the number of fibonacci numbers they want. E.g. inputting 3 should produce 1,1,2 while inputting 5 should produce 1,1,2,3,5.
One way of solving this problem is by using a loop. You will loop as many times as the user requests for, but for the first and second pass through the loop you will print(1).

Question 11 is about patterns, there are two major string patterns - the one with 19 asterisks and the one with 2 asterisks separated by 17 spaces. From the diagram, the default width is 19 asterisks while the default height is 4 asterisks. If a user requests for a box that is 40 asterisks wide by 6 asterisks high, you would use a for loop to print the asterisks 40 times in 6 passes - a nested for loop.
E.g.
for i in range(1, height+1):
for j in range(1, width+1):

Let me see what you will come up with.

Thanks for this input. I won't lie, it took me a while before understanding this

MisterPedro:
First of who asked ?
These online xaiomi touts won't chill at all
You all made your points and successfully derailed infinix on nairaland
But it's enough already if you don't like the phone they bring out shift to your corner shut up and let those who still use infinix enjoy it
At this point point you're all just making people tired of hearing xaiomi this or redmi that

Rest.

Tobitrueman:
I'm all for Redmi o.

If anyone that knows phone and features used Redmi, I don't think they can use any other phone, be it Samsung, Huawei or even IPhone sef.

Mehh, Xiaomi products are dope!!!!

Gave my Redmi note 8 pro out last month.
Just bought the Redmi note 9 Pro.
( I'm still patiently waiting for the MIUI 12 update on this, hopefully it arrives b4 this year ending)

I'm using Redmi Note 8.
Bought it since March. Phone is super cute and cool
Patiently waiting for money to come in to buy the latest one.
The only problem I have with it is that it's an android phone. No room for apple music, iTunes, Spotify, Deezer, Shazam for streaming songs online.
Na so so audiomack and nonsense boomplay
The Google play is ultimately useless

justuschi50:
I swear never in my life buy infinix, Tecno,itel, oppo, xaomi this mobile product are trash

Wtf is Xiaomi doing there? Are u okay?
Remove Xiaomi from there please

naijasensei:
Unfortunately, I don't have links for beginners. Just keep on doing what you are doing. May I suggest studying algorithms and data structures, it will help broaden your understanding a bit.

Hello bro, sorry to disturb.

Please I need a better understanding of question number (9). I've tried so hard to understand what's it all about but I just keep getting a blank idea.

Then, number (11) and (14)

AkupeMBANO:
Nairaland is long dead.

Sorry o. Make Davido news no too pain u

BabaOwen:
On what basis do you think we will vote for you against someone like sowore

Your voting won't matter though ontop Davido

What should we do with this news?
She can't do shit to anyone.

Anyways, 30BG on Nairaland, we feast by 12am.

A better time to make us more happy and enjoy good music.

Ilaumoh:
Senseless post.. Must you over expantiate where he is from?

You didn't read the one caught yesterday in umunze?

progeek37:
Yes, that is a problem. I have similar challenge. If you have solid knowledge in data structures and algorithms you can join my coding WhatsApp group or if you are new you can subscribe to my Zoom tutorial.

Sorry, what's your WhatsApp group?

Lol, I'm not trying to be bad here but op I think you're very wicked. It took me good 10 minutes to read and understand all what u want for ur website and u want to pay just 50k? Damn! This is absolutely bad.
Though as a beginner, I know the length of what you want and 50k is so bad of you.

But wait, isn't the features too much for ur website?

IceColdVeins:
I think you should also tell him the reality of Django's relevance in the Nigerian tech market. smh

is it good or bad?

Karleb:
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.

Yeah it kinda did but I appreciate it them in theory as well. Thanks still

naijasensei:
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.

1, Thanks for clarifying me on that. I thought it was a decimal point. Never knew it was a multiplication operator.
2, I will clearly work on it once more. And I really appreciate the advice.
3, A part of me told me that, but I really tried running that code using for loops, while loops, etc, I just couldn't until I came across functions then I decided to give it a try one more time and boom! it kinda gave me a clue of what I was doing. But it was giving me different answers which did not correspond with the proposed answer. Also, thanks for the advice. I will stick to them.
4, Never knew about PEDMAS. But I knew that python work according to precedence. Just that I didn't really know how that works.

I really appreciate your input.

Lastly, do you have a WhatsApp group or telegram channel for beginners so I could link up and be dropping my troubles as well.

Semtu:
This is a concise answer to your question.

1. One of the reasons functions exist is so you can easily vary parameters. In that sense, it's good programming to pass in arguments when defining the function which you can easily vary later on.
2. Also apply parenthesis using the BODMAS notation

Finally, it seems the question asked for your answer to be in 4 decimal places. So take note of the 'round' method I called, it's an inbuilt python function that accepts two arguments, (float, no of dp)

Wow, this is wow!
Your coding shows how learned you are in programming. I'm yet to grasp all this algorithm in coding but I believe with time I will be able. Thanks for these. It will help me a lot

FadaFran6Xavier:
Greetings.

I’m interested in learning programming (coding)

Greetings too.

I started learning Programming using python programming language. There are many others but if you like python, then u should begin with it. Below is the link to a thread of python video tutorials. It's quite concised and easily understandable.

https://www.nairaland.com/4945611/thread-tutorial-python-programming

Karleb:
Python's '/' always give floating point number (decimal). If you run that 10 times you might get ten different numbers, the only difference will be the numbers after the decimal.

Use '//' to get a non-decimal answer instead.



Try to download an introductory book to python, all these and more are discussed thoroughly there.

Thanks. I really forgot about '//'

Below is the code I ran and the answers I got.

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
