Carefully read the documentation for str.join:
http://docs.python.org/library/stdtypes.html#str.join
How does it work, what does it return, etc. Then fix the corresponding line in
your code.
As a hint: str.join does work quite different than list.sort; I assume you're
confusing their syntaxes.
Good luck,
