Why won't this compile correctly? Python

Question

I am trying to make a game in python. However, when I compile this it says that game isn't defined. can anyone help?

if user_resp == str("start"):
game()
else:
print ("b")
def game():
print("you wake up in a room with two doors")
print("which door will you choose?")
print ("left or right")
user_resp == raw_input
if user_resp == str("left"):
print ("you chose the left door")
elif user_resp == str("right"):
print ("you chose the right door")
else:
print ("that wasnt an option....")

You have to define the method *before* you call it.
