985 PointsWhy is my line 5 wrong?
I don't know how to set store_open = True
store_open = None
store_hours = [9, 10, 11, 12, 13, 14, 15, 16, 17, 18]
time = 12
if time in store_hours:
set store_open = True
else:
set store_open = False

. The grader will assign a value.

33,833 PointsAnswer to this challenge is straight forward: If statement checks store_hours to time (true). Else statement if not in store_hours(false).
store_open = None
store_hours = [9, 10, 11, 12, 13, 14, 15, 16, 17, 18]
if time in store_hours:
store_open = True
else:
store_open = False

store_open = True
will do
