Exercise A:
Write an interactive Python implementation of the "Rock paper scissors" game:
- Ask user for their choice (rock, paper, or scissors). Make sure that the user 
makes a valid choice.
- Compare user input with random computer choice.
- Notify the participant whether they won or lost.

Hint: Python's `random` package and `random.choice()` function may come in handy.
