在定义类方法之前,必须先使用( )进行声明。 A: @classmethod B: @staticmethod C: 不需要事先声明

以下类方法定义正确的是（） A: class Student: fav=("唱歌","跳舞","绘画") def showFav(cls): for item in cls.fav: print(item) B: class Student: fav=("唱歌","跳舞","绘画") @classmethod def showFav(cls): for item in fav: print(item) C: class Student: fav=("唱歌","跳舞","绘画") @classmethod def showFav(cls): for item in cls.fav: print(item) D: class Student: fav=("唱歌","跳舞","绘画") @classmethod def showFav(): for item in fav: print(item)

定义类时,在一个方法前面使用@classmethod进行修饰,则该方法属于类方法

在Python中定义类时，若在一个方法前面使用@classmethod修饰符，则该方法属于静态方法。

在声明一个方法为类的静态方法，需要添加装饰符的名字为（） A: property B: method C: classmethod D: staticmethod

以下类方法定义正确的是（） A: class Student: fav=("唱歌","跳舞","绘画") def showFav(cls): for item in cls.fav: print(item) B: class Student: fav=("唱歌","跳舞","绘画") @classmethod def showFav(cls): for item in fav: print(item) C: class Student: fav=("唱歌","跳舞","绘画") @classmethod def showFav(cls): for item in cls.fav: print(item) D: class Student: fav=("唱歌","跳舞","绘画") @classmethod def showFav(): for item in fav: print(item)
