Lift keypad

#053BasicErrorsConditions5 min

This building has floors 1 to 12, and the lift has a keypad you can type on. Write pick_floor(text): if the text is a number from 1 to 12, return that int; if it isn't a number, or there is no such floor, return None. The floor check is already in the starter.

Examples

pick_floor("5")→5

pick_floor("lobby")→None

pick_floor("15")→None

main.py

def pick_floor(text):
    floor = None
    # your code here: try to turn text into an int in floor; on ValueError leave floor as None
    if floor is None or floor < 1 or floor > 12:
        return None
    return floor
