show() works because it is inside the class Laptop is inside the scope of Students.

you defined the laptop class here: self.lap = Laptop() so anytime the Student's show method is called, it is refered to the Laptop's show method as defined here:
self.lap.show()

None is also shown because show's output is print and not return.
So, call show() like this:
s1.show() # don't add print

Hope this clarifies some things 😃😃
