please help me :(

thanks... do you know how i can fix it now though? i mean, i keep running it and changing minor things, and it keeps giving me the same error :( the error where it says NameError: global name 'tennisPro' is not defined. even though i thought i defined it when i said t = tennisPro() at the very bottom of my code.

self.tennisPro.append(tennisPro("Roger Federer", "1", "18", "SUI", "Wilson"))
needs to be
self.tennisPro.append(tennis("Roger Federer", "1", "18", "SUI", "Wilson"))

It is customary to start class names with an uppercase letter, this way you may not have made this mistake!

Edited 6 Years Ago by Lardmeister: upper

def sort(self, x):

It is bad form to re-define reserved words like "sort" so use a more descriptive name (sort what?) and avoid the confusion. Also, you should include one function at a time and test it, then add another, etc. And why are all of the functions staticMethods? Perhaps I just don't understand the logic.

thanks... do you know how i can fix it now though?

"thanks... do you know how i can fix it now though?"
Re-post the code as a new reply with code tags around it.

Looks like there is a problem with the new page form, i.e ["QUOTE"] does not work.
