Instructions
Objective
Write a program to create card-game in python.
Requirements and Specifications
Instructions:
Suppose we want to be able to place cards back into a deck. Modify the Deck class (will be attached below) to include the operations addTop, addBottom, and addRandom (the last one inserts the card at a random location in the deck). And write unit tests to test the methods suit, suitName and rankNameof Card class in Card.py (Will be attached below).
Source Code
