Simulate Rock, Paper, Scissors Game Between Two Players in Python

Program Overview

This Python program simulates multiple rounds of the Rock, Paper, Scissors game between two players.
Each player chooses one of the following options:
- Scissors → value 1
- Rock → value 2
- Paper → value 3
If both players choose the same option, the round is a draw.
Otherwise, the winner is determined based on the following rules:
- Scissors < Rock → Rock wins
- Rock < Paper → Paper wins
- Paper < Scissors → Scissors wins

Python Code:

# Function to determine winner
def determine_winner(p1, p2):
    if p1 == p2:
        return "Draw"
    elif (p1 == 1 and p2 == 2) or (p1 == 2 and p2 == 3) or (p1 == 3 and p2 == 1):
        return "Player 2 wins"
    else:
        return "Player 1 wins"

# Read number of rounds
n = int(input("Enter number of rounds: "))

# Play each round
for i in range(n):
    print(f"\n--- Round {i+1} ---")
    p1 = int(input("Player 1 (1=Scissors, 2=Rock, 3=Paper): "))
    p2 = int(input("Player 2 (1=Scissors, 2=Rock, 3=Paper): "))
    result = determine_winner(p1, p2)
    print("Result:", result)

Sample Output:

Enter number of rounds: 3  

--- Round 1 ---
Player 1: 1  
Player 2: 2  
Result: Player 2 wins  

--- Round 2 ---
Player 1: 2  
Player 2: 3  
Result: Player 2 wins  

--- Round 3 ---
Player 1: 3  
Player 2: 1  
Result: Player 2 wins

Step-by-Step Explanation:

- Each player inputs a number between 1 and 3
- The determine_winner() function applies the game rules to decide the winner
- If both choices are equal, the round is a draw
- Otherwise, the winner is determined based on the combination
- The result is printed for each round
