def main():

    Game()

main()

when i use this program, no matter what i enter into the python shell, it says the same thing over and over again.. it wont take the raw_input statements into context and put them into the if statements

wow...that is one hell of an if tree. ever consider using a table? — nneonneo

if Enter == "Yes" or "yes":

This is not how or works. This is interpreted as if (Enter == "Yes") or "yes":. In python, non-empty strings are always true, so all of the if statements like that will be true. I would suggest something like

if Enter.lower() == "yes":

which takes care of all of the upper/lower case combinations.

thank you, your suggestion helped in a way. i erased all the or's and it works. it has a few bugs but not as much as before

Matthias Over a year ago

Writing a program like this is one huge bug.

Aaron Dufour Over a year ago

@Matthias Agreed. I would suggest a simple state machine.

Devyn Collier Johnson Over a year ago

If this is Python3.x, use casefold() instead of lower().

Your syntax is wrong here:

if Enter == "Yes" or "yes":

This condition will always be true. Enter == "Yes" is first evaluated. If boolean representation is False, the boolean representation of "yes" will be considered. bool("yes") is always True.

Consider doing something like:

if Enter in ('Yes', 'yes'):

Or:

if Enter.lower() == 'yes':
