Replace Boolean in List in Python (Example)

In this tutorial, you’ll learn how to replace a boolean value in a list with another value in Python. This can be useful when you want to modify specific elements in a list based on their boolean values. We’ll explore different examples to demonstrate this process.

The table of contents is structured as follows:

Let’s get started!

Initializing a Sample List

Firstly, let’s initialize a sample list that contains boolean values:

# Initializing a sample list
my_list = [True, False, True, True, False]

This creates a list, my_list, which contains boolean values.

Example: Replacing a Boolean Value

To replace a boolean value in the list, we can iterate over each element and use conditional statements to identify the boolean value we want to replace. Here’s an example where we replace True with 1 and False with 0:

# Replace True with 1 and False with 0
for i in range(len(my_list)):
    if my_list[i] == True:
        my_list[i] = 1
        my_list[i] = 0
# [1, 0, 1, 1, 0]

In this example, we use a for loop to iterate over each element in the list. Inside the loop, we check if the element is True. If it is, we replace it with 1. Otherwise, we replace it with 0. As you can see, the boolean values in the output list have been replaced with 1 and 0.

In this tutorial, we explored an example of how to replace boolean values in a list with another value in Python. By iterating over the list and using conditional statements, we can modify specific elements based on their boolean values.
