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)
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)
举一反三
- 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)
- class Student: def __init__(self,n="xxx"): self.name=n def show(self): print(self.name) s=Student("yyy") s.show() 结果
- 类方法的隐含参数是（） A: def B: class C: in D: cls
- class Person: def __init__(self,n="xxx"): self.name=n class Student(Person): def __init__(self,s="male"): self.sex=s def show(self): print(self.name,self.sex) s=Student("female") s.show() 结果：
- 以下代码中，实例方法定义正确的是（） A: class Student: def setName(self,name): self.name=name B: class Student: def setName(name): self.name=name C: class Student: def setName(self): self.name=name D: class Student: def setName(name,self): self.name=name
