Python code needed for Question 4

Question 4 (20 points) Assume a game in which two players, A and B, score points and the winner is: . A player who has at least 3 points and wins by at least 2 points or . A player who first scores 7 points. You will write a program that will assist in keeping score of a game Write function point) that prompts the user for a player who wins a point and returns "A" if player A or "B" if player B wins a point. Write function game() that keeps the score in the game and returns "A" if player A wins the game or "B" if player B wins the game Write function main) that calls the previous functions and prints the winner of the game The following diagram shows the structure of the program Question4.py main game point Function point() Prompts the user for the player who wins a point. User enters "A" or "a" for player A, and "B" or "b" for player B Checks input and prints a message in case of invalid input and returns string "E" Returns "A" if player A wins or "B" if player B wins the point. Function game() Initializes the scores of both players to 0 Calls point() to determine the player who wins a point. Increments the score of the player who wins a point. Prints the scores of both players. Game is over and the winner is: .A player who has at least 3 points and wins by at least 2 points or A player who first scores 7 points. Rets "A" if player A wins the game or "B if player B wins the game
