You should read the appropriate manual entries before asking trivial
questions. They say pretty clearly that range returns a list and xrange
an xrange object.
http://docs.python.org/2/library/functions.html#range
http://docs.python.org/2/library/functions.html#xrange
If you do not understand the entries, quote the part that confuses you
and say what you are unclear about.
And which should be used where and in what situations.. ??
The entry for xrange (added after range) tries to explain this. It is
for situations in which one does not want a list, but only the sequence
of numbers, especially in situations where the length of the list would
be large enough to make creating the unneeded list a nuisance.
