Python-based Project for "Rock, Paper, Scissors." !

Below is a complete Python-based project for "Rock, Paper, Scissors." This program allows a user to play against the computer, which makes random moves. It also includes a scoring system to keep track of rounds won by each player.

Features:

1. Randomized Computer Moves: The computer's choice is made using Python's random.choice() function.
2. Input Validation: Ensures that the user enters a valid choice.
3. Score Tracking: Keeps track of the scores for both the user and the computer.
4. Winning Condition: The first player to reach a score of 3 wins the game.
5. Interactive Gameplay: Users get immediate feedback on each round and the current score.

---

How to Run:

1. Copy the code into a Python IDE or text editor (e.g., VS Code, PyCharm, or even IDLE).
2. Save the file as rock_paper_scissors.py.
3. Run the program in your terminal or Python environment using:

   python rock_paper_scissors.py
   

4. Follow the prompts to play!

You can further enhance this project by adding features like:

• Allowing the user to set a custom winning score.
• Adding more choices like "Lizard" and "Spock" for an extended version.
• Implementing a graphical user interface (GUI) using libraries like tkinter or PyQt.
