以下代码编译后，调用错误的是：class Student: def __init__(self,name,age): self.name=name self.age=age def __del__(self): del self.name del self.age print("对象数据删除完毕！")stu=Student("zs",10)
A: stu.name；
B: stu.__init__("李四",20)；
C: del stu；
D: stu.__del__();
A: stu.name；
B: stu.__init__("李四",20)；
C: del stu；
D: stu.__del__();
举一反三
- 写出输出结果：class Student: def __init__( self, name,age=18): self.name=name self.age=agestudent=Student("李强",21)print(student.age)
- class Student:def __init__(self,name,age):self.name=nameself.age=agedef fun1(self):print("hello")（ ）def fun2(self):print("yes")child=Child("Tom",20)child.fun1()
- 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
- 以下有关类的声明，正确的是 A: class Student(object) def __init__(self, name, score): self.name = name self.score = score B: class Student(object) def __init__(self, name, score) self.name = name self.score = score C: class Student(object)： def __init__(self, name, score): self.name = name self.score = score D: class Student(object)： def __int__(self, name, score): self.name = name self.score = score
- {class Student:def __init__(self, name):self.name = namedef out(self):print('name:', self.name)终端应如何输入（创建实例）______、（调用方法）______，使其可以输出“name:王芳”}
