What is the difference between range & xrange?

Hi, What is the difference between range & xrange

Forget about xrange. It doesn’t exist any more.

>>> xrange
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'xrange' is not defined

Use help(range) or read the docs to find out about range.
