Syntax Error

I'm getting the following error in this exercise and I don't know why:

Oh no! An error that I couldn't recover from. Here's what I know: SyntaxError: invalid syntax (<string>, line 9)

membership.py 
time = 15

store_open = None
store_hours = [9, 10, 11, 12, 13, 14, 15, 16, 17, 18]

if time in store_hours
store_open = True
else
if time not in store_hours
store_open = False

Hi there!

Okay a couple of things:

Firstly remember that python groups code together by indentation. when you have an if statement, you have to indent the code that you want to put into the if statement so python knows which code is affected by the if and which code should just be run regardless. Secondly, the three possible parts to and if block are if, elif and else. So say I wanted to greet somebody based on their prefix:

name = input("Please enter your name?")
if "Ms" in name or "Mrs" in name:
    print("Hello Mam!")
elif "Mr" in name:
    print("Hello Sir!")
else:
    print("Hello there {}!".format(name))

Hope it helps :)
