Is Python really slow?

[Mike Fletcher]

>>> v = xrange( 0, sys.maxint )

As this does not require 8GB of memory (4bytes/int), I think you can be
assured that the list is not being created :) . You can deal with the xrange
as though it has created said array, but it's doing lazy evaluation under
the covers to delay creating the numbers until they are needed.

HTH,

Does xrange create an array of numbers 1...1e8?
