python中的perror等价函数

Question

我在python中使用try except block,而try块失败,如何打印有意义的错误消息.我在C中寻找类似perror()的东西

Answer 1

>>> try:
...     0/0
... except Exception,e:
...     print e.message
...
integer division or modulo by zero

或者在Python 2.6及以上版本中e.args,因为BaseException.message has been deprecated

>>> try:
...     0/0
... except Exception,e:
...     print e.args
...
('integer division or modulo by zero',)
