Number Guessing Game in Python

Number Guessing Game is a game in which the computer randomly selects a number between 1 and 100. The user must guess the number within a limited number of attempts. After each incorrect guess, the program provides a hint indicating whether the guess is too low or too high.

In this game, randint() is used to generate a random number within the specified range.

Winning Rules

• Computer generates a random number between 1 and 100.
• User has a maximum of 7 attempts to guess the number.
• User wins immediately if the guess matches the randomly generated number.
• If the guess is lower than the selected number, the program displays "Too Low" and the user should try a higher number.
• If the guess is higher than the selected number, the program displays "Too High" and the user should try a lower number.
• Invalid input or numbers outside the range of 1 to 100 do not count as an attempt.
• If the user does not guess the number within 7 valid attempts, the game ends and reveals the correct number.

Implementation

import random

attempts = 7


def display_rules():
    print("Welcome to Number Guessing Game!\n")
    print("I have selected a number between 1 and 100.")
    print("You have 7 attempts to guess it.\n")


def play_game(number, attempt=1):
    if attempt > attempts:
        print("\nGame Over!")
        print("The correct number was:", number)
        return

    guess = input(f"Attempt {attempt}/7 - Enter your guess: ")

    try:
        guess = int(guess)
    except ValueError:
        print("Please enter a valid number.\n")
        return play_game(number, attempt)

    if guess < 1 or guess > 100:
        print("Please enter a number between 1 and 100.\n")
        return play_game(number, attempt)

    check_guess = lambda x, y: "correct" if x == y else (
        "low" if x < y else "high"
    )

    result = check_guess(guess, number)

    if result == "correct":
        print("\nCongratulations! You guessed the correct number!")
        print("You guessed it in", attempt, "attempt(s).")
        return

    if result == "low":
        print("Too Low! Try a higher number.\n")
    else:
        print("Too High! Try a lower number.\n")

    play_game(number, attempt + 1)


# Start the game
display_rules()

random_number = random.randint(1, 100)

play_game(random_number)

Output:

Explanation:

• Program generates a random number between 1 and 100.
• User gets 7 attempts to guess the number.
• display_rules() displays the game instructions.
• play_game() takes the generated number and handles the guessing process.
• Program checks whether the entered value is a valid number between 1 and 100.
• For each incorrect guess, it displays whether the number is too low or too high.
• If the user guesses correctly, the program displays a congratulatory message and the number of attempts used.
• If all 7 attempts are used, the game ends and displays the correct number.
• check_guess lambda function compares the user's guess with the generated number.
• Function calls itself with the next attempt until the user wins or all attempts are completed.
