python modules tutorial

When working with Python, ensuring your code remains organized and maintainable is of utmost importance. As your software projects grow, they can quickly transform into expansive code bases. One effective way to manage this complexity is by leveraging the power of classes, functions, and notably, modules.

What’s Inside a Module?
Have you ever been curious about the functions and variables a module encompasses? The following Python code snippet reveals the accessible functions and variables inside the sys module:

import sys
print(dir(sys))

Result:

['__displayhook__', '__doc__', ... , 'version', 'version_info', 'warnoptions']

Crafting Your Own Module
Python’s flexibility allows you to construct your own modules effortlessly. Here’s a step-by-step guide:

1. Start by creating a file named test.py, which will serve as your module.

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

2. Subsequently, create a primary file, app.py:

from test import *
print('hello')
print(add(5,2))
