How can you make a function go to another function?

Question

So I have this game:

import sys

def Start():
    print("Hello and welcome to my first Python game. I made it for fun and because I am pretty bored right now.")
    print("I hope you enjoy my EPIC TEXT GAME")

play = input("do you want to play? (Y / N) ")

if play == "Y":
    game()

if play == "N":
    sys.exit()

def game():
    print("That's pretty much what I've done so far! :P -- yea yea, it's nothing -- IT IS!. Bye now")
    input("Press enter to exit")

If I type "Y" I want to go to game(). It doesn't.

Out of curiosity, do you perhpas write "y" (lower-case `y`?) — Torxed, Apr 09 '13 at 12:07
Also, Python version is very important, i assume Python3.X.. — Torxed, Apr 09 '13 at 12:08
Assume it's python 3 because of print function, so input() is ok here — wim, Apr 09 '13 at 12:08

You have defined game after you tried and use it. You need to define functions, variables, etc. before you use them. Also, your code only matched on upper case Y and not lower case y. To make all input upper case, you should use the .upper() method on it
Change the code to:

def game():
    print("That's pretty much what I've done so far!")
    input("Press enter to exit")

if play.upper() == "Y":
    game()
elif play.upper() == "N":
    sys.exit()

It is usually best form to not have any global code, and instead include it in a main function if the python code is being run as the main. You can do this by using:

if __name__ == "__main__":
    Start()

And then put all that global code into the Start method. Again, make sure you declare before you use.

No problem. you should consider looking at [Learn Python The Hard Way](http://learnpythonthehardway.org/book/) to get all this juicy knowledge. — Serdalis, Apr 09 '13 at 12:11

You're using the input() function which executes the input as a command immediately after reading it from stdin.

You probably want to use raw_input() which will simply return what the user entered

This is python 3.0 which does not have `raw_input` (you can tell by the print statement). – Serdalis Apr 09 '13 at 12:14
The print function is valid in Python 2.7 as well. I didn't know about the input/raw_input change in 3.x. Thanks. – BradS Apr 10 '13 at 00:51
