Indeed, I didn't know about xrange(), just range(). Useful little tidbit to know.

For those who want type safety in Python, you can always do something like this:
Code:
Try to pass in anything but an int or long for the first argument, or anything but an int for the second argument, and it will throw an assertion error. The Filter should, as far as I know, work for any type - user defined or built in, it shouldn't matter
Code:
def Filter(*types):
def wrapper(func):
def check(*args):
assert len(types) >= len(args)
for i in range(len(args)):
assert isinstance(args[i], types[i])
return func(*args)
return check
return wrapper
@Filter((int,long), int)
def Add(a, b):
return a + b
Try to pass in anything but an int or long for the first argument, or anything but an int for the second argument, and it will throw an assertion error. The Filter should, as far as I know, work for any type - user defined or built in, it shouldn't matter
