🐍 Python Basics: Mastering Functions—Write Cleaner, Smarter Code

1. What is a Function?

A function is a reusable block of code that performs a specific task. Instead of repeating code, you define a function once and call it whenever needed.

⚡ Defining a Function

You define a function using the def keyword.

⚡ Calling a Function

To execute a function, you simply call its name followed by parentheses:

2. Function Parameters & Arguments

Functions become more powerful when they accept inputs!

⚡ Positional Arguments

You can pass values (arguments) into a function.

⚡ Default Arguments

Set default values for parameters to make them optional.

⚡ Keyword Arguments

Specify arguments by name for better readability.

3. Returning Values from Functions

A function can return data instead of just printing it.

4. Advanced Function Tricks

⚡ Multiple Return Values

A function can return multiple values as a tuple.

⚡ Variable-Length Arguments (*args & **kwargs)

Use *args for multiple positional arguments.

Use **kwargs for multiple **keyword arguments**.

⚡ Lambda Functions (One-Liner Functions)

Use lambda for short, anonymous functions.

5. Challenge: Function Power-Up!

Write a function that takes a list of numbers and returns a new list with only the even numbers. Drop your solution in the comments! 💡
