问题：Python：一次尝试多项

在Python中，except一个try语句是否可以有多个语句？如 ：

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

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

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()

请参阅：http : //docs.python.org/tutorial/errors.html

关键字“ as”用于将错误分配给变量，以便稍后可以在代码中更彻底地调查错误。另请注意，在python 3中需要三重异常情况的括号。此页面具有更多信息：在一行中捕获多个异常（块除外）

Yes, it is possible.

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()

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

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)
