如何重新启动在python中循环? [英] how to restart "for" loop in python ?

问题描述

如何在python中做到这一点?

How can I do this in python:

x = [1,2,3,4,5,6]
for i in x:
    if i == 4:
       -restart the loop from beginning-
    else:
        print i

所以在这里它将打印到4，然后重复循环

So here it will print till 4 then repeat the loop

推荐答案

这是怎么回事:

x = [1,2,3,4,5,6]
restart = True
while restart:
    for i in x:
        # add any exit condition!
        # if foo == bar:
        #   restart = False
        #   break
        if i == 4:
           break
        else:
            print i
