def winner_RPS(p1, p2): if p1 == p2: return None if (p1 == "paper" and p2 == "rock") or \ (p1 == "scissors" and p2 == "paper") or \ (p1 == "rock" and p2 == "scissors"): return p1 return p2

For this question, we are going to tidy up this solution by enforcing the following best practices:

1. Create the constants ROCK, PAPER, SCISSORS and update the code accordingly (i.e. there should only be one 'rock' in your code)

2. Have only a single exit point in the function. That is there should only be one return statement

3. Properly name the variable that you return (the one that holds the winner of RPS.
