Nested decisions

Python · Unit 2: Conditionals

An if can go inside another one. The inner one is only checked if the outer one was met.

Each level takes 4 more spaces of indentation.

age = 70
if age >= 18:
    print("Adult")
    if age >= 60:
        print("With discount")

Prints

Adult
With discount
