NameError: global name 'xrange' is not defined in Python 3
...) was renamed to range() in Python 3.
Run the game with Python 2 instead. Don't try to port it unless you know what you are doing, most likely there will be more problems beyond xrange() vs. range().
For the record, what you are seeing is not a syntax error but a runtime exception instead.

What is the formal difference in Scala between braces and parentheses, and when should they be used?

(-2147483648> 0) returns true in C++?

if (ptr)
free(ptr);
This is because some C runtimes (I for sure remember it was the case on PalmOS) would crash when freeing a NULL pointer.
