[Yashjain0099]

This pull request addresses and resolves the issues identified in the Rock-Paper-Scissors game code, improving gameplay flow and accuracy.

Changes Made:

Corrected Data Type Mismatch: Replaced random.randint() with random.choice() for the computer's choice, ensuring direct selection of "rock," "paper," or "scissors" and preventing integer-string comparison errors.

Improved Game Logic: Modified the game loop to allow continuous play until a clear win or loss is determined, with proper handling of ties.

Added Input Validation: Ensured that user input is validated, prompting users to enter only valid choices ("rock," "paper," or "scissors") to prevent unintended behavior.

Refactored Code Structure: Enhanced readability with consistent indentation and streamlined conditions to make the game logic more intuitive and maintainable.

Outcome:
These changes result in smoother, error-free gameplay and provide users with a clearer and more reliable Rock-Paper-Scissors experience.
