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。我正在寻找像C

中的perror（）之类的东西

Answer 1

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

或在Python 2.6及更高版本中，e.args，因为BaseException.message has been deprecated

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

Answer 2

try:
   pass
except Exception, err:
   print err
