python 如何try 多次

Question

try：
    do someting
except：
    os._exit(0)

比如执行do someting 时有错误，我想再试两次，如果两次执行还是有错误，那就os._exit(0) 退出

我找到方法了，分享出来

import os
attempts = 0
success = False
while attempts < 3 and not success:
    try:
	do something
	success = True 
    except:
	attempts += 1
	if attempts==3:
	    os._exit(0)
