What are Python modules and how do I use them?

Python modules are files containing Python code. They can define functions, classes, and variables. You can use them by importing.

How do I create my own module?

To create a module, simply write your functions and classes in a .py file. You can then import this file in other Python scripts.

Can you show me an example of a simple module?

Sure! Create a file named mymodule.py with a function like this:

def greet(name):
    return f'Hello, {name}!'

You can import it using import mymodule.

How do I import specific functions from a module?

You can import specific functions using the from keyword. For example:

from mymodule import greet

This allows you to use greet() directly.
