time = 15

store_open = None
store_hours = [9, 10, 11, 12, 13, 14, 15, 16, 17, 18]
if time is in store_hours: store_open = True
    if time is not in store_hours: store_open = False

First there is not IS second you should use IF and ELSE not IF IF.

The word 'is' is not a keyword, you only need to use 'in' or 'not in' to check for inclusion.

if time in store_hours:
    store_open = True
