traceback.print_last([ limit [,file ] ] ) 这是一个简写。通常,只有在异常达到交互式提示后才会起作用(请参阅参考资料)。print_exception(sys.last_type, sys.last_value, sys.last_traceback, limit, file)sys.last_type traceback.print_stack([ f [,limit [,file ] ] ] ) 此函数从其调用点打印...
print(sys.exc_info()[2]) ``` 这将打印出traceback对象。 3. 如果您只有异常对象,您可以使用`traceback.format_exception()`来获取traceback¹: ```python import traceback try: 1/0 except Exception as e: print(''.join(traceback.format_exception(None, e, e.__traceback__))) ``` 这将...
