Functions

Functions let you package code into reusable units. Instead of repeating the same logic, you define it once and call it whenever needed. Defining Functions Steps to Define a Function Building a function follows a consistent pattern. Each step adds a layer of clarity to how the function works. Parameters are the variable names in the function definition. Arguments are the actual values you pass when calling the function. Keyword arguments allow callers to pass values by name, making function calls self-documenting and removing the need to remember argument order. Functions are first-class objects in Python. You can assign them to variables, pass them as arguments to other functions, and return them from other functions.
