Function Parameters and Arguments in Python

Functions become much more useful when they can work with different information on every call. This Block explains the difference between parameters and arguments, then shows how values move from a function call into its body.

What you will learn:

• Define functions that accept one or more parameters
• Pass arguments using direct values, variables, and simple expressions
• Match several arguments to parameters by position
• Use clear parameter names and keep argument order predictable
• Combine strings, numbers, booleans, and lists inside reusable functions
• Recognize missing, extra, and incorrectly ordered arguments

By the end, you will be able to write flexible functions that receive the information they need and use it in clear, predictable ways.
