Functions

🧠 Functions help you organize code into reusable pieces. Once defined, you can call a function whenever you need its behavior—just like pressing a button.

Defining a Function

Use the def keyword to define a function.

Parameters and Arguments

You can pass data into functions using parameters.

Return Values

Use return to send a result back to the caller.

Default Parameter Values

You can give parameters default values.

Keyword Arguments

You can pass arguments by name, in any order.

Variable Number of Arguments

Use *args for any number of positional arguments.

Use **kwargs for any number of keyword arguments.

Functions Returning Multiple Values

You can return more than one value using tuples.
