Generating Random Boolean Values in Python: A Comprehensive Guide

Python is a popular language that offers a lot of built-in tools that make it easy to perform complex operations with minimal code. Generating random boolean values, true or false, can be a challenging task, which is why we have compiled this comprehensive guide that outlines the four common methods that you can use to generate random boolean values in Python

Using random.getrandbits() method

Random.getrandbits() is a built-in function in Python that returns an integer representing a random n-bit integer.

A boolean value can be returned by extracting the least significant bit of the getrandbits() integer using the boolean() function. Here’s how to generate a random boolean value using the random.getrandbits() method.

Code Snippet:

import random

boolean_value = bool(random.getrandbits(1))

Using random.randint() method

The random.randint() method returns a random integer N such that a<=N<=b, where a and b are the parameters passed to the method. To generate a random boolean value using random.randint(), we can use 0 and 1 as the range values, and then convert the integer value to a boolean value using the boolean() function.

Here’s an example:

Code Snippet:

import random

boolean_value = bool(random.randint(0, 1))

Using random.choice() method

Random.choice() is a method that returns a randomly selected element from a non-empty list. We can create a list with two elements: True and False, and then use the random.choice() method to select one randomly and return it as a boolean value.

Here’s the code:

Code Snippet:

import random

boolean_value = random.choice([True, False])

Using random.choices() method

Random.choices() is similar to the random.choice() method but returns a list of randomly selected elements from a non-empty list with replacement. To generate a random boolean value using the random.choices() method, we need to specify two elements in the list and a weight for each value.

Here’s how:

Code Snippet:

import random

boolean_value = random.choices([True, False], weights=(1, 1), k=1)[0]

Comparison of the Four Methods

All the methods presented above have their unique features and advantages. The random.getrandbits() method is the most straightforward method to generate a random boolean value, while random.choices() offers the most flexibility.

On the other hand, random.randint() and random.choice() are simple yet effective methods for generating random boolean values.

Usage of Different Methods

The choice of which method to use will depend on the specific scenario, the end goal, and personal preference. However, if performance is a top priority, then the random.getrandbits() method would be the best option.

However, if you want a more flexible and versatile option, the random.choices() method is the way to go. In any case, the four methods presented above are all viable and can be used in a wide range of scenarios.


Generating random boolean values is an interesting task in Python, given the language’s flexibility and built-in tools. The four methods discussed in this guide provide a wide range of options to generate random boolean values, depending on the scenario and the end goal.

By now, you should be confident in choosing the best method that suits your needs. In conclusion, generating random boolean values in Python is a common task for developers, and there are several methods to choose from, each with its own advantages and flexibility.

We discussed four methods, including using random.getrandbits(), random.randint(), random.choice(), and random.choices(). Choosing which method to use depends on the specific scenario’s requirements and the developer’s personal preference.

Nevertheless, these methods offer solutions that can be used in various scenarios. Remember to choose the method that best suits your needs and continue exploring other built-in functions Python offers.
