class Person: def __init__(self,name):self.name=name def __str__(self):return "我的名字是"+self.nameperson=Person("小明")print(person)编译能通过吗，如果通过写出结果，否则写出失败原因
举一反三
- 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
- 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)
- 定义类的代码如下：class Person():def __init__(self,name):self.name=namedef show(self):print(self.name) A: p=Personp.show() B: p=Person()p.show('李思') C: p=Person('李思')p.show() D: p=Person('李思')show()
- 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()
