python - __add__ operator what am i doing wrong? -

i have add 2 names using overloading operator add. output should both names added example: "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 

what doing wrong?

the error get:

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' 

a person object has aname should pass currect object self , added object:

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