python异常捕获try except
python的异常处理机制设计的比较传统,在日常的开发中,基本满足我的需要
下面就python的异常,几点小小的讨论
tommy@lab3:~$ python
Python 2.5.2 (r252:60911, Jan 4 2009, 17:40:26)
[GCC 4.3.2] on linux2

>>> 1/0
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ZeroDivisionError: integer division or modulo by zero
>>>
>>> try:
... 1/0
... except:
... print "do something..."
...
do something...
>>>
2. try...finally
finally 里面只是执行完成try中的代码后,必须执行的代码,
即使是 try中有异常抛出,也是会去执行finally
>>> try:
... 1/0
... finally:
... print "I just finally do something ,eg: clear!"
...
I just finally do something ,eg: clear!
