## 通用装饰器
def PrintData(func):
    def inner(*argvs,**kwargcs):
        print('printData ')
        x = func(*argvs,**kwargcs)
        return x
    return inner

## 带参数的装饰器
def Argv_Fun(argv):
    def PrintData(func):
        def inner(*argvs,**kwargcs):
            print('printData Argv_Fun')
            print(argv)
            x = func(*argvs,**kwargcs)
            return x
        return inner
    return PrintData
