@retry def do_something(): result = something_else() if result == 23: raise TryAgain 5、错误处理 虽然默认情况下“超时”重试的可调用对象会引发RetryError,但如果需要,我们可以重新引发最后一次尝试的异常: @retry(reraise=True, stop=stop_after_attempt(3)) def raise_my_exception(): raise MyExcep...
Finally,trystatements can say "finally"-- that is, they may include finally blocks. These look like except handlers for exceptions, but the try/finally combination specifies termination actions that always execute "on the way out," regardless of whether an exception occurs in the try block. 最...

如果try中语句执行时发生异常,却没有匹配的except子句,异常将被递交到外层的try,如果外层不处理这个异 常,异常将继续向外层传递。如果都不处理该异常,则会传递到最外层,如果还没有处理,就终止异常所在的线程 如果在try执行时没有发生异常,如有else子句,会执行else子句中的语句 无论try中是否发生异常,finally子句...
:keyword:`try` statement is finished. 如果没有异常发生, *except 子句* 在 :keyword:`try` 语句执行完毕后就被忽略了。 * If an exception occurs during execution of the try clause, the rest of the clause is skipped. Then if its type matches the exception named after the ...
Python Try, Except, Else and Finally Block Thefinallyclause can appear always after theelseclause. It does not change the behavior of the try/except block itself, however, the code under finally will be executed in all situations, regardless of if an exception occurred and it was handled, or...

Try again Division by 0 not accepted Executing finally block Out of try, except, else and finally blocks. In the third run case, an uncaught exception occurs. The finally block is still executed but the program terminates and does not execute the program after the finally block....
