exiting

I have tried my code many different times, each one a little different, but no matter how many times I try my code, the same error message keeps popping up. It says: 'Didn't get an exit from start_movie', or something like that. Can someone please tell me what I am doing wrong!

firedoor.py 
import sys

var = input("Do you want to start the movie right now? ")
if var != "n" or "N":
    print("Enjoy the show!")
else:
    sys.exit()

In addition to Alex's solution you can also do it like this

# Indicate that yes is the default value in case the user doesn't enter anything
var = input("Do you want to start the movie right now? (Y/n)")

# the lower() method will take the input string and convert it to lower case
if var.lower() != 'n':
   print("Enjoy!")

Good one! I knew that you could do that, but I don't like to make my answers too complicated for new students :smile:

This should work: 

import sys

var = input("Do you want to start the movie right now? ")

if var.lower() != "n":
    print("Enjoy the show!")
else:
    sys.exit()

You can't use the "or" operator like this:

var != "n" or "N"

but you can use it like this:

var != "n" or var != "N"

So this means you should fix your condition, and then this should work:

import sys

var = input("Do you want to start the movie right now? ")

# I fixed the condition! :)
if var != "n" or var != "N":
    print("Enjoy the show!")
else:
    sys.exit()

Hope this helps and Happy coding! ~Alex :smile:

I tried what you recommended, and I understand what I did wrong, but the same error message keeps popping up: Didn't get an exit from start_movie. I still cannot understand what I did wrong. If it helps, here are the instructions for the code challenge:

Use input() to ask the user if they want to start the movie. If they answer anything other than "n" or "N", print "Enjoy the show!". Otherwise, call sys.exit(). You'll need to import the sys library.

I had difficulties in this problem too. However, I fixed it, giving one enter to import sys and the rest of the code, too. I hope this help.
