For loop with custom steps in python

Question

I can make simple for loops in python like:

for i in range(10):

However, I couldn\'t figure out how to make more complex ones, which are re

Answer 1

You need to use a generator. You could implement this as follows:

def stepDown(n):
    while n>1:
        yield n
        n = n/2

for i in stepDown(n):
    print i # or do whatever else you wish.

Note that this generalizes easily to other complicated patterns you may have in mind.
