Snake Water Gun game using Python and C

Difficulty Level : Easy
Last Updated : 08 Feb, 2021

Snake Water Gun is one of the famous two-player game played by many people. It is a hand game in which the player randomly chooses any of the three forms i.e. snake, water, and gun. Here, we are going to implement this game using python.

This python project is to build a game for a single player that plays with the computer

Following are the rules of the game:

Snake vs. Water: Snake drinks the water hence wins.
Water vs. Gun: The gun will drown in water, hence a point for water
Gun vs. Snake: Gun will kill the snake and win.
In situations where both players choose the same object, the result will be a draw.

We will use random.choice() method and nested if-else statements to select a random item from a list.

Below is the implementation:

Python3

# Import random module
import random
print('Snake - Water - Gun')
 
 
# Input no. of rounds
n = int(input('Enter number of rounds: '))
 
 
# List containing Snake(s), Water(w), Gun(g)
options = ['s', 'w', 'g']
 
# Round numbers
rounds = 1
 
# Count of computer wins
comp_win = 0
 
# Count of player wins
user_win = 0
 
 
# There will be n rounds of game
while rounds <= n:
 
    # Display round
    print(f"Round :{rounds}\nSnake - 's'\nWater - 'w'\nGun - 'g'")
 
    # Exception handling
    try:
        player = input("Chose your option: ")
    except EOFError as e:
        print(e)
 
    # Control of bad inputs
    if player != 's' and player != 'w' and player != 'g':
        print("Invalid input, try again\n")
        continue
 
    # random.choice() will randomly chose
    # item from list- options
    computer = random.choice(options)
 
    # Conditions based on the game rule
    if computer == 's':
        if player == 'w':
            comp_win += 1
        elif player == 'g':
            user_win += 1
 
    elif computer == 'w':
        if player == 'g':
            comp_win += 1
        elif player == 's':
            user_win += 1
 
    elif computer == 'g':
        if player == 's':
            comp_win += 1
        elif player == 'w':
            user_win += 1
 
    # Announce winner of every round
    if user_win > comp_win:
        print(f"You Won round {rounds}\n")
    elif comp_win > user_win:
        print(f"Computer Won round {rounds}\n")
    else:
        print("Draw!!\n")
 
    rounds += 1
 
 
# Final winner based on the number of wons
if user_win > comp_win:
    print("Congratulations!! You Won")
elif comp_win > user_win:
    print("You lose!!")
else:
    print("Match Draw!!")
