python - 捕获异常时,如何获取类型、文件和行号?

捕获会像这样打印的异常:Traceback(mostrecentcalllast):File"c:/tmp.py",line1,in4/0ZeroDivisionError:integerdivisionormodulobyzero我想把它格式化成:ZeroDivisonError,tmp.py,1 最佳答案 importsys,ostry:raiseNotImplementedError("Noerror")exceptExceptionase:exc_type,exc_obj,exc_tb=sys.exc_info()fname
