class A is an instance of class B, and class B is an instance of class A. class A is an instance of itself. These relationships between object and type (both being instances of each other as well as themselves) exist in Python because of "cheating" at the implementation level.▶...
To do this, the class implements a .__contains__() method that relies on the in operator itself. To try out your class, go ahead and run the following code: Python >>> from stack import Stack >>> stack = Stack() >>> stack.push(1) >>> stack.push(2) >>> stack.push(3) ...
