for or while loop to do something n times

Question

In Python you have two fine ways to repeat some action more than once. One of them is while loop and the other - for loop. So let\'s have a look on

Answer 1

This is lighter weight than xrange (and the while loop) since it doesn't even need to create the int objects. It also works equally well in Python2 and Python3

from itertools import repeat
for i in repeat(None, 10):
    do_sth()
