X次运行流程的更多Pythonic方式 [英] More Pythonic Way to Run a Process X Times

问题描述

哪个更pythonic?

Which is more pythonic?

循环时:

count = 0
while count < 50:
    print "Some thing"
    count = count + 1

For循环:

for i in range(50):
    print "Some thing"

不重复，因为这可以确定哪个更清晰，而不是如何在不使用"i"的情况下运行范围-即使最终以最优雅的方式出现

not duplicate because this has answers to determine which is clearer, vs. how to run a range without 'i' -- even though that ended up being the most elegant

推荐答案

个人:

for _ in range(50):
    print "Some thing"

如果您不需要 i .如果您使用Python<3，并且您想重复很多次循环，请使用 xrange ，因为不需要事先生成整个列表.

if you don't need i. If you use Python < 3 and you want to repeat the loop a lot of times, use xrange as there is no need to generate the whole list beforehand.
