Functions

Lesson

What is a function?

• range() and len() are functions!
• These have pre-defined behavior
• Allow you to input something then return something
• Example: range takes 1 or 2 numbers as input then returns a list

How do we create one?

• Line 1: def {functionName} ({inputs}):
• Line 2+: tab, then operations to perform
• (optional) last line: return 1+ variables!
• Use function using its name and passing in the inputs you defined

Function options

• You can introduce optional inputs/arguments (see Playground for example)
• Use as many inputs and outputs as you need, just remember order is important!
