异常统一捕获

继承自Motor类,可实现python代码在任何地方抛出异常都能被捕获并记录,避免程序异常退出时没能记录现场。

1 from abc import abstractmethod, ABC
 2 import traceback 
 3 class Motor(ABC):
 4   @abstractmethod
 5   def customize(self)->int:
 6     pass

7   @abstractmethod 8   def destroy(self): 9     pass 10 11 @abstractmethod 12   def handle_exception(self, exp, msg): 13     #log.info(msg) 14 15 @abstractmethod 16   def run(self): 17     ret = 1
      try:
        ret = self.customize()
      except Exception as e:
        msg = traceback.format_exc()
        self.handle_exception(e, msg)
      finally:
         self.destroy()
      exit(ret)
class MyMotor(Motor):
  #实现除run以外的其他函数


m = MyMotor()
m.run()
