pythonic way to do something N times without an index variable?
Question: Every day I love python more and more.

Today, I was writing some code like:

    
    
    for i in xrange(N):
        do_something()
    

I had to do something N times. But each time didn't depend on the value of `i`
(index variable). I realized that I was creating a variable I never used
(`i`), and I thought "There surely is a more pythonic way of doing this
without the need for that useless index variable."

So... the question is: do you know how to do this simple task in a more
(pythonic) beautiful way?


Answer: A slightly faster approach than looping on `xrange(N)` is:

    
    
    import itertools
    
    for _ in itertools.repeat(None, N):
        do_something()
