Python继续 [英] Python continue with while

问题描述

在Python中继续操作似乎存在一些严重的问题: 例如:

There seems to be some serious problem with continue in Python: for eg:

for i  in range(1,10):
    if i % 2 == 0:
         continue
     print i

可以正常工作，但是

i = 0

while(i < 10):
    if i %2 == 0:   
        continue
    i += 1
    print i

while循环永远不会终止！

the while loop never terminates!

推荐答案

您的while循环与您的for循环的作用不同； for循环从 1 开始，并且始终递增i.

Your while loop does not do the same thing as your for loop; the for loop starts at 1 and always increments i.

在偶数测试之前将i += 1 移动:

i = 0

while(i < 10):
    i += 1
    if i % 2 == 0:   
        continue
    print i

因为0 % 2 == 0是True，所以您总是继续，跳过i += 1和print i语句.

because 0 % 2 == 0 is True, so you always continue, skipping the i += 1 and print i statements.
