[ Python: loop error in Python Programming for Absolute Beginner "games" module ]

I'm learning Python and have hit a snag in this code. I have even pulled down the author's code and it has the same problem. :(

After importing the "random" module and the "games" module, which includes the "ask_number()" function and the class definition for a "Player," we have:

again = None
while again != "n":
    players = []
    num = games.ask_number(question = "How many players? (2-5): ", low = 2, high = 5)
    for i in range(num):
        name = input("Player name: ")
        score = random.randrange(100) + 1
        player = games.Player(name, score)
        players.append(player)

The "ask_number()" function looks like this:

def ask_number(question, low, high):
    """Ask for a number within a range."""
    response = None
    while response not in range(low, high):
        response = int(input(question))
    return response

When the program is run, however, the question "How many players? (2-5):" appears ad infinitum, regardless of what number is input as a response. Clearly it seems some kind of erroneous loop has been set up, but I can't figure out what it is for the life of me (that's why I'm an "absolute beginner," haha!).

Thanks in advance for returning my sanity to me! :)

EDITED: Since I thought the problem was merely with the syntax of the ask_number() function, I didn't want to append a lot of extraneous code. Learned that lesson! :) This is the full loop, so it does seem that again has a changeable value. (Note that the "ask_yes_no()" function is also in the "games" module.)

again = None
while again != "n":
    players = []
    num = games.ask_number(question = "How many players? (2-5): ", low = 2, high = 5)
    for i in range(num):
        name = input("Player name: ")
        score = random.randrange(100) + 1
        player = games.Player(name, score)
        players.append(player)
    print("\nHere are the game results:")
    for player in players:
        print(player)
    again = games.ask_yes_no("\nDo you want to play again? (y/n): ")

Answer 1

you are saying

while again != "n":

but you never set again! Because again never equals 'n' it never exits the loop

Answer 2

You are never changing the value of again. In order to fix this you could add this

again = raw_input("Play again?: ")

at the end of the while loop.
