Brief Explanation:

1. Imports: o random: Used to generate random choices for the computer.

2. Choices List: o choices = ["Rock", "Scissors", "Paper"]: Defines the possible choices for the game.

3. Function get_user_choice: o This function prompts the user to choose Rock, Scissors, or Paper. o It validates the input to ensure the user enters a valid choice (1, 2, or 3). o It returns the corresponding choice from the choices list.

4. Main Game Loop: o The game runs in a loop, allowing for multiple rounds of 5 games each until the user decides to exit. o It initializes user_score and computer_score to zero for each round of 5 games. o Prompts the user to start the game or exit.  If the user chooses to start (1), it plays 5 rounds:  For each round, it gets the user's choice and randomly selects the computer's choice.  It compares the choices and updates the scores based on who wins or if it's a draw.  After 5 rounds, it displays the final scores and the overall winner.  If the user chooses to exit (2), it exits the loop and ends the game.  If the input is invalid, it prompts the user again.

5. Game Logic: o If the choices are the same, it's a draw. o The user wins if their choice beats the computer's choice according to the game rules. o Otherwise, the computer wins. This structure ensures a clear and user-friendly game flow, with proper input validation and clear separation of different parts of the game logic
