你能“重启"吗?Python循环的当前迭代?

Can you quot;restartquot; the current iteration of a Python loop?(你能“重启吗?Python循环的当前迭代?)

问题描述

有没有办法实现这样的东西:

Is there a way to implement something like this:

for row in rows:
    try:
        something
    except:
        restart iteration

推荐答案

你可以把你的 try/except 块放在另一个循环中，然后在它成功时中断:

You could put your try/except block in another loop and then break when it succeeds:

for row in rows:
    while True:
        try:
            something
            break
        except Exception: # Try to catch something more specific
            pass
