Scene when such, I have a lot of tasks, I want to give these 任务计时 , warehousing. An adorner with parameters is required to record the 任务 name, and it is necessary to document the time the task was executed before and after the task was executed.

#-*-encoding=utf-8-*- fromFunctoolsImportWraps def task_logging(taskname):     def func_wrapper(func):        @wraps (func)         def return_wrapper(*args, **wkargs):            # The function transmits parameters to the adorner by decorating the parameters            Print ' before Task ', TaskName# Decorator Pass variable to functionTaskID =1Summer, Funcres = Func (TaskID, *args, **wkargs)Print ' after Task ', TaskID, SummerreturnFuncresreturnReturn_wrapperreturnFunc_wrapper@task_logging ("test") def testd(taskid):    Print "Testd runing", TaskIDreturn "task summer success EG", []PrintTESTD ()
