displaystu1.display(),stu2.display()
举一反三
- 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__();
- 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
- 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
- {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”}
- Student是一个学生类，其构造函数的声明为def __init__(self, name, score)，对Student类进行实例化生成对象stu1，正确的是 A: stu1 = Student('xiaoming',89) B: stu1 = Student(stu1,'xiaoming',89) C: xiaoming = Student(stu1,89) D: stu1 = Student(89,'xiaoming')
