Python function that only has print output?

I'm trying to create a function in python that outputs a menu like this:

MENU

p) Play the matching penny game

q) Quit

What I've tried...

def display_menu():
    print "###MENU###"
    print "p) Play the matching penny game"
    print "q) Quit"

I want to call the function in a script and have the menu displayed, but it doesn't display in the shell nor does it throw an error. How do I go about doing this?

The function you wrote is 100% fine for what you want. The problem is that you aren't calling it at all during execution. If your program is going to be complex, I'd suggest creating a main function where everything major takes place, the heart of your program, and calling that via:

if __name__ == "__main__":
    main()

Otherwise you can have it called however you want, as long it the function is executed at runtime, which it currently isn't.

you probably need parentheses around your text..

def display_menu():
    print ("###MENU###")
    print ("p) Play the matching penny game")
    print ("q) Quit")
display_menu()

I guess you forgot to call the display_menu function. Try this:

def display_menu():
    print "MENU".center(10, "#")
    print "p) Play the matching penny game"
    print "q) Quit"

if __name__ == "__main__":
    display_menu()

def display_menu():
    print "###MENU###"
    print "p) Play the matching penny game"
    print "q) Quit"

display_menu()    # call the function

You have to actually call the function in order for it to run.
