  • I understand correctly that you want the buyer to make a “familiarize with the shop window” method, where the input will be the shop window class? - Eugene Dennis
  • @EugeneDennis I need to make a product purchase method - the method takes as input the number of product units and the name. - Merk G9
  • and where is the showcase? - Eugene Dennis
  • @EugeneDennis in the showcase class stores the name of the product, its cost and quantity. All this data needs to be passed to the User.Buyer class. - Merk G9
  • The answer was given an example of transferring attributes between classes, does not suit you? - Eugene Dennis

It is not entirely clear that, after all, it is really necessary to pass a class parameter to another class or a class instance parameter to an instance of another class. If, after all, you need exactly what is indicated in the question header, then such a scheme can work:

 class c1(): c1str='blahblah' def __init__(self): pass class c2(): def __init__(self): self.c2str=c1().c1str print(c2().c2str)

Displays:

 blahblah
