How To Simulate Rolling Dice In Python

In this tutorial, we will learn how to simulate rolling dice in Python. Simulating dice rolls can be helpful in various applications, such as for games, statistical analyses, or testing the fairness of dice. We will be using the built-in Python library random to create our dice rolls.

Step 1: Import the Random Library

First, we need to import the random library in our Python code. This library provides various functions for generating random numbers.

Step 2: Define the Number of Sides on the Dice and the Number of Rolls

Next, we will define variables for the number of sides on the dice and the number of rolls we want to simulate. For the standard six-sided dice, we can use the following code:

You can change the values here to simulate dice with a different number of sides or a different number of rolls.

Step 3: Roll the Dice

We can now use the randint function from the random library to generate random numbers representing the dice rolls. The randint function accepts two arguments, the lowest and highest number you want to generate (inclusive).

In our case, we want to generate numbers from 1 to the number of sides on the dice. We can use a for loop to generate the specified number of rolls, like this:

This code will print the result of each roll in the specified range.

Full Code

Here is the full code for simulating the dice rolls using the random library:

Sample Output

Roll 1: 3
Roll 2: 6
Roll 3: 5
Roll 4: 1
Roll 5: 4
Roll 6: 2
Roll 7: 2
Roll 8: 6
Roll 9: 1
Roll 10: 5

The output shows the result of each simulated dice roll. Keep in mind that since this is a random process, your output might be different.


In this tutorial, we covered how to simulate rolling dice using Python and the random library. With just a few lines of code, we were able to generate random dice rolls, which can be useful in various applications such as games, statistical analyses, or testing the fairness of dice.
