我正在用python学习类，在执行代码时，我得到以下错误
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'
我知道这是一个非常基本的问题，但我无法在网上找到解决方案
只要不给laptop的init（）方法添加参数，它就会工作:D。
