请执行以下代码，说明错误出现的行数。1. class Dog(object):2. def __init__(self,name):3. self.name = name4. @property5. def eat(self):6. print(" %s is eating" %self.name)7. 8. d = Dog("wangwang")9. d.eat()知识点：属性的定义和使用
举一反三
- 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”}
- 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()
- 定义类如下：class Hello(): def __init__(self,name): self.name=name def showInfo(self): print(self.name)下面代码能正常执行的 （ ）。 A: h = Helloh.showInfo() B: h = Hello()h.showInfo('张三') C: h = Hello('张三')h.showInfo() D: h = Hello('admin')h.showInfo
