Question

I would like to separate my functions into different files like I do with c++ (a driver file and a file for different categories of functions that I end up linking together upon compilation).

Let’s suppose I want to create a simple ‘driver’ file which launches the main program and a ‘function’ file which includes simple functions which are called by the driver and other functions within the ‘function’ file.

How should I do this? Since python is not compiled, how do I link files together?

Answer 1

You can import modules. Simply create different python files and import them at the start of your script.

For example I got this function.py file :

def func(a, b):
    return a+b

And this main.py file:

import function

if __name__ == "__main__":
    ans = function.func(2, 3)
    print(ans)

And that is it! This is the official tutorial on importing modules.
