2.抛出的异常应该说明原因,有时候你知道异常类型也猜不出所以然的。 3.避免在catch语句块中干一些没意义的事情。 4.不要使用异常来控制流程,那样你的程序会无比难懂和难维护。 5.如果有需要,切记使用finally来释放资源。 6如果有需要,请不要忘记在处理异常后做清理工作或者回滚操作。 速查表 你想更深入了解学...

# Handle I/O errors except Exception as e: # Handle other exceptions finally: # Cleanup, runs no matter what 异常是按层次结构组织的,如果发生了IOError会执行IOError的except代码,剩下的异常则交由Exception处理。理解这个层次结构可以根据需要更广泛或更具体地捕获错误。
