__add__运算符我做错了什么？

Question

我必须使用重载运算符添加将两个名称添加到一起。我的输出应该是两个名字加在一起，例如：“john”+“frank”='JohnFrank'

class Person():
    def __init__(self, name):
        self.aname = name


    def __add__(self,other):
        x = self.person1 
        y = self.person2 
        print(x + y)
        return(Couple(x,y))

class Couple(Person):
    def __init__(self,person1,person2):
        self.person1 = person1
        self.person2 = person2

我做错了什么？

我得到的错误：

Traceback (most recent call last):
  File "<pyshell#81>", line 1, in <module>
    acouple = p1 + p2
  File "/Users/Desktop/NameP.py", line 7, in __add__
    x = self.person1
AttributeError: 'Person' object has no attribute 'person1'

Answer 1

Person对象只有aname，因此您应该传递当前对象self和添加的对象：

def __add__(self, other):
    return Couple(self, other)

Answer 2

# This is what worked for me


class Person():
    def __init__(self, name):
        self.aname = name


    def __add__(self,other):
        x = self.aname 
        y = self.aname 
        print(self.aname + " " + other.aname)
        return(Couple(x,y))


class Couple(Person):
    def __init__(self,person1,person2):
        self.person1 = person1
        self.person2 = person2
