Question

class studnt:
def __init__(self,name,rno):
self.name = name
self.rno = rno
self.laptop = self.laptop()

def show(self):
print(self.name,self.rno)
self.laptop.show
class laptop:
def __init__(self,brand,cpu,ram):
self.brand = "ASUS"
self.cpu = 10
self.ram = 8  
def show(self):
print(self.brand,self.cpu,self.ram)
s1 = studnt("rishabh",100)
s2 = studnt("hanuman",1000)
s1.show()

我在python中学习课程，在执行代码时，我得到了以下错误

Traceback (most recent call last):
File "classw.py", line 21, in <module>
s1 = studnt("rishabh",100)
File "classw.py", line 5, in __init__
self.laptop = self.laptop()
TypeError: __init__() missing 3 required positional arguments: 'brand', 'cpu', and 'ram'

我知道它非常基本的问题，但我无法在网上找到解决方案

Answer 1

只是不要把params放在笔记本电脑的__init__()方法中，它应该可以工作：D。

class studnt:
def __init__(self,name,rno):
self.name = name
self.rno = no
self.laptop = laptop()
def show(self):
print(self.name, self.rno)
self.laptop.show() 
class laptop:
def __init__(self):
self.brand = "ASUS"
self.cpu = 10
self.ram = 8  
def show(self):
print(self.brand, self.cpu, self.ram)
s1 = studnt("rishabh", 100)
s2 = studnt("hanuman", 1000)
s1.show()
