Python
异常处理机制和 C# 类似
>>> try:
raise Exception("a", "b")
except Exception, e:
pr
e
finally:
pr "finally..."
('a', 'b')
finally...同样可以处理多个异常筛选
>>> try:
raise Exception("a", "b")
except RuntimeError, e:
pr "[RuntimeError]", e
except EOFError, e:
pr "[EOFError]", e
except Exception, e:
pr "[Error]", e
finally:
pr "finally..."
[Error] ('a', 'b')
finally...除了异常参数
我们还可以用sys
些思路方法来获取异常信息>>> import sys
>>> try:
raise Exception("a", "b")
except:
pr sys.exc_info
(<type 'exceptions.Exception'>, Exception('a', 'b'), <traceback object at 0x00D37A80>)缺省情况下
异常类都继承自 Exception>>> import sys
>>> 
MyException(Exception):
pass
>>> try:
raise MyException
except:
pr sys.exc_info
(< '__
__.MyException'>, MyException, <traceback object at 0x00D37AA8>)
