python抛出raise异常的注意点

class CustomError(Exception):

  def __init__(self,ErrorInfo):

    super().__init__(self) #初始化父类

    self.errorinfo=ErrorInfo

  def __str__(self):

    return self.errorinfo

if __name__ == '__main__':

  try:

    raise CustomError('客户异常')

  except CustomError as e:

    print(e)

客户异常
