异常后如何重试? [英] How to retry after exception?

问题描述

我有一个以for i in range(0, 100)开头的循环.正常情况下，它可以正常运行，但有时由于网络条件而失败.目前，我已对其进行了设置，以便在失败时将在except子句中显示为continue(继续使用i的下一个数字).

I have a loop starting with for i in range(0, 100). Normally it runs correctly, but sometimes it fails due to network conditions. Currently I have it set so that on failure, it will continue in the except clause (continue on to the next number for i).

是否可以将相同的数字重新分配给i并再次执行失败的循环迭代?

Is it possible for me to reassign the same number to i and run through the failed iteration of the loop again?

推荐答案

在for循环内执行while True，将try代码放入内部，仅在代码成功后才从while循环中断. /p>

Do a while True inside your for loop, put your try code inside, and break from that while loop only when your code succeeds.

for i in range(0,100):
    while True:
        try:
            # do stuff
        except SomeSpecificException:
            continue
        break
