Python 2.5 long

P: 20
I have this bit of code, which I copied from my book;
Expand|Select|Wrap|Line Numbers
  1. def checkIndex(key):
  2.     if not isinstance(key,(int, long)): raise TypeError
  3.     if key < 0: raise IndexError
But I am currently using Python 3.1, does anyone knows what long is in Python3? Because I am getting an error saying long is not defined, and when I try in Python 2 it works

Python integers don't have a length, so use int only. If you have huge numbers, then use the decimal class which can handle both extremely small and extremely large numbers. Try this snippet as a test:
Expand|Select|Wrap|Line Numbers
  1. x_int = int("123")
  2. print len(x_int)

int and long are unified as int in Python 3.X. See PEP 237.
