Tennis Python Kata

Overview

This kata complements Clean Code: Fundamentals, Ep. 4 - Function Structure.

The rules of the tennis kata are as follows:

• The game is played by two players, called "Player 1" and "Player 2".
• The players start with a score of 0 points each.
• The players take turns hitting the ball over the net, with Player 1 serving first.
• The game continues until one of the players reaches a score of 4 points.
• If a player reaches a score of 4 points, they must have a lead of at least 2 points over the other player in order to win the game. For example, if player 1 has a score of 4 and player 2 has a score of 3, the game continues.
• If the scores are tied at 4 points each, the game enters the "Deuce" mode. In deuce mode, the players continue to play until one of them has a lead of 2 points.

For more information on the rules of tennis, please see the official rules from International Tennis Federation.

Instructions

To complete the kata, your code should include the following features:

• A function that keeps track of the score for each player: this function should be able to increment the score for a player when they win a point.
• A function that returns a string representation of the current score.

The rules for scoring representation are as follows:

• If both players have the same number of points, the score is described as "Love-All", "Fifteen-All", "Thirty-All", or "Deuce" depending on the number of points scored.
• If one player has scored four or more points and has a two-point lead over the other player, the score is described as "Win for Player 1" or "Win for Player 2" depending on which player has won.
• If one player has scored four or more points and has a one-point lead over the other player, the score is described as "Advantage Player 1" or "Advantage Player 2" depending on which player has the advantage.
• If both players have scored less than four points, the score is described as "Love", "Fifteen", "Thirty", or "Forty" depending on the number of points scored by each player.
