pythonic方式做某事N次没有索引变量？ [英] pythonic way to do something N times without an index variable?

问题描述

我每天都喜欢python越来越多。

Every day I love python more and more.

今天，我正在写一些代码：

Today, I was writing some code like:

for i in xrange(N):
    do_something()

但每次不依赖于 i （索引变量）的值。
我意识到我创建了一个我从来没有使用的变量（ i ），我想肯定有一个更多的pythonic方式，那无用的索引变量。

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."

所以...问题是：你知道如何以更美丽的方式做这个简单的任务？ >

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

推荐答案

在 xrange（N） p>

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

import itertools

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