Zabiboy:


No H.F man...
But the question is straight forward...
We're not here to compete...all this explanation would just make a novice think these things are hard....
Scientific computing is not a real life application....it's just like telling a non-programmer that a real life application of python is back-end programming...it wont make sense to him...Simply saying "Python is used to make a website functional" would be better...

That being said, you aren't the only one that has done this tho...i just felt i had to point it out..

Can you please tell me the application of "Numpy" in real life?

Hello Gurus in the house. I need your help here.

I am trying to work Git Bash to run python commands

I already have Git installed but when i ran these commands

echo 'export PATH="$PATH:/c/Users/Nelly/anaconda3:/c/Users/Nelly/anaconda3/Scripts"' >> .bashrc

echo 'alias python="winpty python.exe"' >> .bashrc


I get the errors below:

bash: export: `=': not a valid identifier
bash: export: `:/c/Users/Nelly/anaconda3:/c/Users/Nelly/anaconda3/Scripts': not
a valid identifier

Whenever i launch Git Bash, i get the error below:


bash: export: `=': not a valid identifier
bash: export: `:/c/Users/Nelly/anaconda3:/c/Users/Nelly/anaconda3/Scripts': not
a valid identifier
bash: alias: python: not found
bash: alias: =: not found
bash: alias: winpty python.exe: not found

What could be the problem?

I have searched stackoverflow, but the solutions i saw there did not help me to resolve the fault.

I am wondering if anyone has experienced it

shegzhkn:


Tried that my friend, thanks i appreciate your input.
Gracias

shegzhkn:


How ?, elaborate.

shegzhkn:
Python is an object oriented programming language along side language like Java, C++, C#, etc

one of the concept of OOP is polymorphism allowing object to be created in different form.

Now here is the real deal, Java support Constructor overloading the same for C# but you have to be creative to do that in python say use of default value in the init method.

But i needed to create an object of a class in different form and using default value will not cut it or make it work the way i wanted it to.

So can I create another class with similar logic with slight discrepancies from the former and i am considering efficiency here.

Thanks

I have seen a lot of web developers portfolio on twitter and one thing that stands out mostly is the to do list and the calculator. Most web developers seem to have this on their portfolio websites?

Do this projects make one employable. I tried doing the to do app and it took like 8 lines of Javascript. Is it wise to include something so basic on ones portfolio?

Good day Pals. Please I have been trying to install Django in my system since yesterday but it's been futile.

I mean, I have used my sytem command prompt, Anaconda prompt, pycharm command prompt by typing

"pip install django"

but they all return the same message that reads:

"Could not find a version that satisfies the required django(from version: )
No matching distribution found for django."


Please what could be the problem
I already have installed Python, Anaconda which has Jupyter notebook, I also have pycharm.

Please someone should help a brother profer a solution.

Or is Django something I have to download separately before installing it??

Hello Guys,

As i mentioned earlier. Below is another one from fiverr. The budget is $108. My objective is purely for us to discuss and for people to see real life data science problems that people pay for to be solved for them

I do not even know how to solve this one. I hope out gurus in the house can use it to teach us. Just give us an idea of how to approach it.


>>>>> hi Everybody, I looking for someone for Machine Learning sequence prediction models who are not afraid from numbers & big numbers, So the work will be analyse a file with more then 32000 results of raffles. Each raffle is include 4 cards, Heart, Diamond, Clubs and Leaf. So in each raffle there are result for each cards, means 4 results. Now I think that on this file there is something that return and based on old results new result is coming. There is not pattern or something, you should find something like that. After we success to predict the next raffle, I need it automate, so every time I will load the new CSV it will predict the next results. Do you think you can handle this big file and try to found some algorithm or solution to get high accuracy of the results in next raffle? I've attached here the CSV file with the results. I also know the next raffle result, so let me know if you can predict the results. What I need from you is a "demo" or predict the next raffle results and we compare the results with the real results. Regards.<<<<<

What do you mean by Dom??

Thanks for this,

I have been trying to scrape a certain car selling website (not like nairaland that load all its details once) but the website is such that as you scroll down it keeps bringing information for new cars. When I tried to scrape it, it only gave me the information for 10 cars alone.
Is there a way to do it that it will give me more cars information.

lymelyte:
the circled file is the csv file

lymelyte:
Please check out this double dot csv.is it right?

DAramis:

Thanks for the effort. I did it but didn't work. You can write the full code for me to have an idea if my request is not to much.
Below is the code:

secretName = 'Joe'
name = input ('What is your name?')
while name != secretName:
    name = input ('What is your name?')
    break
    secretPassword = 'swordfish'
    password input ('What is your password?')
    while password != secretPassword:
        password = input ('What is your password?')

secretName = 'Joe'
name = input ('What is your name?')
while name != secretName:
    name = input ('What is your name?')

secretPassword = 'swordfish'
password = input (f'Hello, {secretName}. What is the password? (It is a fish.)')
while password != secretPassword:
    password = input (f'Hello, {secretName}. What is the password? (It is a fish.')
Print('Acess granted')

ThePlainTruth:

This is my new handle.
The task below which I posted before is what is relevant to this thread and it is a real world business requirement.

 [Write a program that will allow me from the program you write to execute another program on a remote computer and when the program has completed on the remote computer the program you write should be able to accept a return code from the program on the remote computer.

Hello bosses and Madams,
Someone should help me out in this python program (I justed started learning it but was stuck in this assignment). The question is in red while my answer is in blue.

Who are you?
I'm fine, thanks. Who are you?
Who are you?
Joe
Hello, Joe. What is the password? (It is a fish.)
Mary
Who are you?
Joe
Hello, Joe. What is the password? (It is a fish.)
swordfish
Access granted.

My code (though not running)

name = ''
While not name:
print ('Who are you?')
name = input ()
while name != 'Joe':
print ('Who are you?')
break
print ('Hello Joe. What is the password?' (it is fish))
password = input ()
while password != 'swordfish'
print ('Hello Joe. what is the password?' (it is fish))
break
print ('Access granted')

Very VERY good write up.
Most people fail to realise that the theory you learn during your Computer Science class goes a long way in furnishing your competency. I am still a CS student and I'm proud of that and I know it is not a waste of time.
You can never compare a CS student to someone who went to a bootcamp. They just dont compare. And to those Self taught coders that exaggerate and that think they are far better than CS student, OYO is your case. A lot of master invention are product birthed by CS students themselve. CS student establish the engine/core while self taught developer build on the engine. Your knowledge of some CS stuff along the years will make you a better programmer in any field of your choice.
Rob Pike co-creator of Go, UTF-8 was a CS student.
Dennis Ritchie co-creator C prog lang, co-creator of UNIX OS, co-creator of B prog lang was a CS student.
Ken Thompson creator of B programming lang,co-creator C prog lang, co-creator of Go, co-creator of UTF-8 was a CS student he is known for UNIX OS that is one of the foundation of modern computing.
Sergery Brin co-founder of Google and X was a CS student.
.
To every self-taught developer(that might think CS studying is a waste of time and effort), I want us play to a little game.
* Explain the internal workings of a compiler, and the possible phases a compiler can have.

* Explain briefly the Architecture of the CLR (Common Language Runtime), JIT(Just In Time) Compilation.
* What three core operation does a basic compiler work with.
* Write a simple Fibonacci series algorithm, where it will print out the series to the 20th term and where you can specify the nth term you desire.
* Write a simple algorithm that can give out the ASCII values you inputted
* Find the 2's complement of 11111000, 11001010, 6A3D, E9F
* As related to x86 architecture find the bit and hexadecimal of the following IP address 127.0.0.1, 956.56.0.0(use little endianess) .
* Briefly explain the internal working of cdecl, fastcall, stdcall. And which does Windows use for callng DLLs and APIs
* List out the possible components that enables Win32 API to access the Kernel Mode of a basics Windows NT Operating system, Briefly explain Native API as related to Windows OS.
.
Note this is for FUN.

shadeyinka:

The issue is that a vast majority of CS graduates are completely useless when it comes to problem solving and practicals except those who develop themself outside the Nigerian school curriculum.

One expects to see CS graduates making waves in solution provision but alas, self taught (including self taught CS graduates) are the king.

CS curriculum is too abstract and useless for now in Nigeria. It is one thing to understand data structures and OS, it is completely another thing to know how to IMPLEMENT the theories

There's room for everyone. The CS graduate specialising in software engineering, is responsible for the high level thinking process required for software design, algorithms, architecture and planning. They then hand down this design and plan to the programmers who do the coding with the programming language of their choice or of the company's choice. Everyone knows their place.
