How much ram does your machine have?
the main point is "except when a very large range is used on a
memory-starved machine"
run
x = range(10 ** 6)
and look at the memory usage of python..
what happens when you run this program:
import time
def t(func, num):
s = time.time()
for x in fun

"The advantage of xrange() over range() is minimal (since xrange()
still has to create the values when asked for them) except when a very
large range is used on a memory-starved machine or when all of the
range's elements are never used (such as when the loop is usually
terminated with break)." - f
