Python: One Try Multiple Except(Python:一次尝试多次，除了)

本文介绍了Python:一次尝试多次，除了的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在 Python 中，一个 try 语句是否可以有多个 except 语句?如:

In Python, is it possible to have multiple except statements for one try statement? Such as :

try:
 #something1
 #something2
except ExceptionType1:
 #return xyz
except ExceptionType2:
 #return abc

推荐答案

是的，有可能.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

参见:http://docs.python.org/tutorial/errors.html

as"关键字用于将错误分配给变量，以便稍后在代码中更彻底地调查错误.另请注意，python 3 中需要三重异常情况的括号.此页面包含更多信息:一行捕获多个异常(block除外)

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)
