Python Guess the Number Game Project: Solutions and Explanations

Guess the Number Game:

Make a game where the computer generates a random number, and the player has to guess it.

Input and Output values:

Input values:
Player guesses the randomly generated number.

Output value:
Feedback on whether the guess is correct, too high, or too low. Repeat until the correct number is guessed.

Example:

Input values:

Enter your guess: 7

Output value:

Too low! Try again.

Input values:

Enter your guess: 12

Output value:

Too high! Try again.

Input values:

Enter your guess: 10

Output value:

Correct! You guessed the number.

Here are two different solutions for the "Guess the Number" game in Python. Both solutions will have the computer generate a random number, and the player will attempt to guess it until they are correct, with feedback provided for each guess.

Solution 1: Basic Approach using a While loop

Code:

# Solution 1: Basic Approach Using a While Loop

# Import the 'random' module to generate a random number
import random

# Generate a random number between 1 and 100 (inclusive)
secret_number = random.randint(1, 100)

# Initialize a variable to store the player's guess
guess = None

# Start a loop that continues until the correct guess is made
while guess != secret_number:
    # Get the player's guess and convert it to an integer
    guess = int(input("Enter your guess: "))

    # Check if the guess is less than the secret number
    if guess < secret_number:
        print("Too low! Try again.")
    # Check if the guess is greater than the secret number
    elif guess > secret_number:
        print("Too high! Try again.")
    # If the guess is correct, congratulate the player
    else:
        print("Correct! You guessed the number.")

Output:

Enter your guess: 12
Too low! Try again.
Enter your guess: 19
Too low! Try again.
Enter your guess: 50
Too high! Try again.
Enter your guess: 35
Too low! Try again.
Enter your guess: 45
Too high! Try again.
Enter your guess: 40
Too low! Try again.
Enter your guess: 42
Too low! Try again.
Enter your guess: 43
Too low! Try again.
Enter your guess: 44
Correct! You guessed the number.

Explanation:

• Uses a while loop to repeatedly prompt the player for their guess until they guess correctly.
• The random.randint(1, 100) function generates a random number between 1 and 100.
• After each guess, the program checks if the guess is too low, too high, or correct and provides appropriate feedback.
• This approach is simple and effective, using a loop for repeated guesses.

Solution 2: Using a Function and Recursion

Code:

# Solution 2: Using a Function and Recursion

# Import the 'random' module to generate a random number
import random

# Generate a random number between 1 and 100 (inclusive)
secret_number = random.randint(1, 100)

# Define a function to handle the guessing logic
def guess_number():
    """Recursive function to guess the number."""
    # Get the player's guess and convert it to an integer
    guess = int(input("Enter your guess: "))

    # Check if the guess is less than the secret number
    if guess < secret_number:
        print("Too low! Try again.")
        # Call the function recursively to ask for another guess
        guess_number()
    # Check if the guess is greater than the secret number
    elif guess > secret_number:
        print("Too high! Try again.")
        # Call the function recursively to ask for another guess
        guess_number()
    # If the guess is correct, congratulate the player
    else:
        print("Correct! You guessed the number.")

# Start the guessing game by calling the function
guess_number()

Output:

Enter your guess: 20
Too low! Try again.
Enter your guess: 30
Too high! Try again.
Enter your guess: 25
Too high! Try again.
Enter your guess: 22
Too high! Try again.
Enter your guess: 21
Correct! You guessed the number.

Explanation:

• Uses a recursive function guess_number() to handle the guessing logic.
• The function calls itself recursively after each guess if the guess is incorrect (either too low or too high).
• If the guess is correct, the function prints a congratulatory message and stops further recursion.
• This approach demonstrates the use of recursion to achieve the same outcome, providing a different way to handle repeated prompts.

Note:
Both solutions achieve the desired outcome of a "Guess the Number" game, with Solution 1 using a loop-based approach and Solution 2 using recursion to repeatedly ask for the player's guess. The recursive approach may be less efficient for large numbers of guesses due to potential stack overflow. However, it demonstrates a different way of structuring program logic.
