Python novice asks questions about attributes in classes

Question

code show as below:

# -*- coding:gb2312 -*-

class Home:
    def __init__(self,new_name,new_area,new_addr,new_info):
        name = new_name
        area = new_area
        addr = new_addr
        info = new_info
    def __str__(self):
        return ("房子的户主是：%s，面积是：%d平米，地址是：%s，户型是：%s。"%(self.name,self.area,self.addr,self.info))


class Bed:
    def __init__(self):
        pass
    def __str__(self):
        pass

fangzi = Home("谢霆锋",182,"香港","三室一厅")
print(fangzi)

operation result:

My question:
The system prompts: return ("The owner of the house is: %s, the area is: %d square meters, the address is: %s, and the house type is: %s." %(self.name,self.area,self.addr,self.info))
She said that the attribute name cannot be found in this paragraph, but I clearly wrote it in init. I checked it inside and out many times but still can't figure it out.

Answer 1

def __init__(self,new_name,new_area,new_addr,new_info):
        self.name = new_name
        self.area = new_area
        self.addr = new_addr
        self.info = new_info
        

You need to add attributes to the self object. It doesn’t just have to be written.
