Number Guessing Game

The random module

In order to generate or random numbers, we need to use the built-in Python module random. It's used for generating random data, such as random integers and choosing random elements from a list.

Generating Random Numbers

In the random module, we have a useful function called randint which takes two parameters (two numbers), a and b, and generates a random integer (whole number) between them inclusive. So, for example, I could run randint(5, 10) and get 5, 6, 7, 8, 9, or 10. This is what we are going to use in our game.

Using randint

We've already discussed how randint works, so now let's implement our game!

But, before we start using randint and the random module, we'll need to import it. We can simply do this by writing

import random

After, we can access the randint function using random.randint.

So, therefore, we can generate a random number between 1 and 100 using

num = random.randint(1, 100)

We save the number into the variable num for use in our game

Implementing The Game

First, we want a while loop for our game, so the user can enter guesses over and over until they get it. And, before the loop, we will add the randint code.

import random
num = random.randint(1, 100)   
while True:
    guess = int(input("Guess A Number Between 1 and 100: "))
    

After, we just need to add some if statements for the logic:

import random
num = random.randint(1, 100)
while True:
    guess = int(input("Guess A Number Between 1 and 100: "))
    if guess > num:
        print("Your Number Is Too High. Try Again!")
    elif guess < num:
        print("Your number Is Too Low. Try Again!")
    else:
        print(f"Correct! The Number Was {str(num)}.")
        break
    

We want to tell the player if they guessed too low, too high, or if they got the number! We can just use some quick if-statements.

You can also find the code here.

And then, you're done. Congrats!

Extensions

Fun extension ideas:

• Give the user a limited number of guesses
• Add a feature for hints on the number (even or odd, etc.)
• Allow the player to replay after guessing the number
• Add a points system
• Let the user quit in the game
• Make a version of the game using a graphical user interface
