Modules & Imports

1What Are Modules?✨

Modules are files containing Python code that can define functions, classes, and variables. They help organize code, making it reusable and easier to manage.

2Creating a Module🎯

To create a module, simply save your code in a file with a .py extension. For example, create a file named `math_operations.py` with the following code:

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

def subtract(a, b):
    return a - b

3Using Modules💡

You can use your module in another Python file by importing it. Here's how to use the `math_operations` module:

import math_operations

result_add = math_operations.add(5, 3)
result_subtract = math_operations.subtract(10, 4)

print(result_add)        # Outputs: 8
print(result_subtract)   # Outputs: 6

4Benefits of Using Modules🚀

• ✓ Promotes code reusability
• ✓ Keeps your code organized
• ✓ Makes collaboration easier
• ✓ Helps manage larger projects

5Importing Specific Functions🔍

Sometimes, you only need specific functions from a module. You can import them like this:

from math_operations import add

result = add(7, 2)
print(result)  # Outputs: 9

6Creating Your Own Project⭐

Now that you understand modules and imports, try creating a small project! Organize your code into multiple modules, like one for math operations and another for string manipulations. This will help you practice and see the power of modular programming!
