__add__问题，请帮忙

python---1

class A:
    def __init__(self,x):
        self.x = x
        
    def __add__(self,other):
        other.x = x
        return self.x + other.x

    def __radd__(self,other):
        return self.x
   
    def __iadd__(self,other):
        return self.x + other.x-2
   
   
>>> a = A(42)
>>> b = A(3)
>>> a+b
Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    a+b
  File "D:\2pythonproject\lei类__add__等运算.py", line 6, in __add__
    other.x = x
NameError: name 'x' is not defined
为什么啊

def __add__(self,other):
        other.x = x
        return self.x + other.x
这里哪有x 啊  人家提示x没定义，没毛病啊

python---1

谢谢，已明白，删掉 other.x = x
