Python Functions

Python Functions are named blocks of reusable logic. In Brevvie Python + AI — Section 1: Setup Your IDE, they are introduced as the first step beyond top-to-bottom scripts. In Brevvie Python + AI — Section 2: Control Flow & The Treasure Hunt, they become the main container for parsing data, describing objects, and building the recursive Hunter.

Why they matter

• package repeated logic behind a name
• accept input through parameters
• return values to callers
• make code easier to test, reuse, and combine

Course progression so far

• Section 1: basic def, parameters, return values, and main()
• Section 2: functions that accept dicts, class instances, strings, and nested collections
