Jujutsu is a game is played by two opponents, each starting with cards numbering from 1 to 13. There are also 13 treasure cards, also numbered from 1 to 13. (Clearly, this game can be played with three suits of a standard deck of cards.) The treasures are shuffled, and revealed one at a time. After each treasure is revealed, each player selects one card; they are revealed at the same time. The higher card wins the treasure, unless a 1 and a 13 are played, in which case the 1 wins. If two cards with the same number are played, nobody gets the treasure. At the end of the game, the player with the most treasure points wins.

This is a coding assignment for students with around one year's experience in Python.

The card chooser function is the heart of the assignment: this is a Python function which is passed two arguments: a state object and this player's name, and which returns an integer representing the player's choice. The rest of the framework is provided; students' task is to write their own card chooser function. Once this is done, they can start a server which plays this function.

treasure: the integer value of this turn's treasure
history: an array of turn objects (earliest turn first), each containing the following keys
playerOneName: the integer value of the card this player played
playerTwoName: the integer value of the card the opponent played
treasure: the integer value of the turn's treasure

Here is an example state object:

{
    "treasure": 4,
    "history": [
        {
            "treasure": 6,
            "Polly": 12,
            "Molly": 5
        },
        {
            "treasure": 11,
            "Polly": 11,
            "Molly": 10
        }
    ]
}

It will be good to build a shared library of helper functions for commonly-performed tasks. For example, players will almost always want to figure out what cards they still have in their hands; to do this they will need to iterate through the state history to figure out what has already been played.

• Need to understand lists, dicts, and functions well
• Functions as arguments to other functions
• deconstructing large project into smaller projects
• Error handling?
• Types, particularly ints vs strings
• Allowing computers to interact with each other will be new and exciting.
