How to use different external methods in a class method?

Question

Python

Hello! The task is this: to implement the RSA class, in which there will be different checks for simplicity, exponentiation, etc. to measure the final speed of execution. The idea came up like this: Implement the methods of the used operations and checks in the parent class, the child will have an implementation of RSA. However, then how to make different instances of the child class? That is, for example, there is an encryption method. It needs to be raised to a power. How to make the erection different (self-written and pythonic, for example)? Do not rewrite the same method again.

Answer 1

To do this, there is a redefinition of methods, when the heir overlaps the implementation of the parent.
This requires making the child class abstract and making 2 descendants from it with different definitions of the encryption algorithm.
If you don't want to do this, make 2 different encryption methods and name them according to the applied algorithm.
