(x)range( 40000000000, 40000000001 )

[Chris Connett]

It seems range and xrange don't like longs that can't be sqeezed into ints:

With Python 2.3b1+:

xrange( 40000000000, 40000000001 ) Traceback (most recent call last):
File "<stdin>", line 1, in ?
OverflowError: long int too large to convert to int range( 40000000000, 40000000001 ) Traceback (most recent call last):
File "<stdin>", line 1, in ?
OverflowError: long int too large to convert to int

Its not a critical problem, and I can find a way around it. It's a just
little disconcerting that (x)range doesn't work with big longs, and it
seems it would not be too difficult to make work.

This is intentional.
xrange() is meant to be a fast, lightweight alternative to range().
It has been given the minimum possible functionality.
Use range() or a generator to meet other needs.

The first problem is that range is designed to create a list and the
canonical usage for range is range(N); lists cannot currently have more
than int elements. xrange() could get away with fixing it, but Guido has
decreed that xrange() is a target for deprecation (and will go away in
Python 3.0), so he won't allow any improvements to xrange() in order to
encourage people to use alternatives.
