Python-自定义异常

#coding:utf8
import sys
class MyException(Exception):
    def __init__(self, value):
        Exception.__init__(self)
        self.value = value

    def __str__(self):
        return self.value
def raise_ex(args):
    if args == 'err':
        raise MyException('Invalid name is %s' % args)
    else:
        print('name: %s' % args)
 
if __name__ == '__main__':
    name = input('请输入name：')
    try:
        f = raise_ex(name)
    except Exception as e:
        print('type %s ' % type(e))
        print('sys info: %s' % sys.exc_info()[0])
        print(e)

结果

请输入name：err
type <class '__main__.MyException'> 
sys info: <class '__main__.MyException'>
Invalid name is err
