it's a 2.5 addition.  to use this in a "future-compatible" way in 2.3, 
you can add

     try:
         any
     except NameError:
         def any(iterable):
             for element in iterable:
                 if element:
                     return True
             return False

to the top of the file (or to some suitable support library).

2.5 also provides an "all" function, which can be emulated as:

     try:
         all
     except NameError:
         def all(iterable):
             for element in iterable:
                 if not element:
                     return False
             return True
