python try except

一个简单的例子

In [3]: int('11')
Out[3]: 11
In [4]: int('11.11')
...
ValueError
...

加入 try except:

In [5]: try:
   ...:     int('11')
   ...: except:
   ...:     print('something wrong')
   ...:
In [6]: try:

...:     int('11.11')

...: except:

...:     print('something wrong')

...:

something wrong
In [8]: try:

int('11.11')

except Exception as e:

print('something wrong: %s' % e)

...:

something wrong: invalid literal for int() with base 10: '11.11'
In [9]: try:

int('11.11')

except ValueError as e:

print('something wrong: %s' % e)

...:

something wrong: invalid literal for int() with base 10: '11.11'
In [10]: try:

int('11.11')

except ZeroDivisionError as e:

print('something wrong: %s' % e)

....:
ValueError                                Traceback (most recent call last)
 in ()
      1 try:
----> 2     int('11.11')
      3 except ZeroDivisionError as e:
      4     print('something wrong: %s' % e)
      5
ValueError: invalid literal for int() with base 10: '11.11'
