Your First if

An if statement runs a block of code only if a condition is True. Notice the colon : and the indented line underneath — that indented part only runs when the condition holds:

age = 20
if age >= 18:
    print("You can vote!")

If age were 10 instead, nothing would print at all.

Your turn: read a number age. If age is 18 or more, print You can vote! — otherwise, print nothing.
