# Just by looking at the output, it seems pretty obvious that xrange
would be more memory effcient for large ranges:
print "With range():",range(100,200)
print
print "With xrange():",xrange(100,200)
d = {1:2,2:3,3:4}
d.items()
d.iteritems()
# I have been curious to use Pysizer (which requires patching Python)
to demonstrate the difference.

When is it appropriate to use dict.items() vs dict.iteritems. Both
seem to work for something like:
for key,val in mydict.items():
print key,val
for key,val in mydict.iteritems():
print key,val
Also, when is it appropriate to use range() vs xrange(). From my
understanding, xrange() essentially gives you an iterator across a
range, so it should be used when iterating. Should you only use
range() when want to physically store the range as a list?
Thanks,
Drew
