Sophie's Python practice games

In order to practice Python, Sophie worked on some Python that implements a game.

Deck shuffle

The first practice was to figure out how to take an ordered list of cards and shuffle that list like a deck of cards. After quickly figuring out a way to shuffle cards and then display the mixed up deck, she worked on making a guessing game out of it.

This deck_shuffle was written using the Windows 11 installation of Python 3.12.1 and its IDLE shell and editor.

----------------------------------------------------------------------++--------

deck_shuffle.py

"""
Named deck_shuffle, but includes a card suit guessing game.

In order to practice Python, we started with a set of cards and
implemented a way to shuffle them. Then we thought of a game we could
implement. Two player Go Fish would be tricky as keeping each player's
hand secret was difficult to implement. As this was implemented to run
in IDLE Shell and we weren't sure how to clear the screen between turns
we thought hot-seat players would too easily scroll up to view other
players' information. Therefore a no-knowledge guessing game was added.

Two players take turns guessing all 52 cards' suits of a shuffled deck.
Good scores make 13 or better correct guesses if card counting.

Some basic color support was added when run in IDLE.
