Replace Element at Certain Index in List in Python (Example)

In this tutorial, you will learn how to replace an element at a specific index in a list in Python. There are situations where you may want to update or modify a particular element in a list without changing the rest of the elements. We will 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 to work with:

# Initializing a sample list
my_list = [10, 20, 30, 40, 50]

This creates a list named my_list containing five elements.

Replace an Element at a Certain Index

To replace an element at a specific index in the list, you can directly assign a new value to that index using the assignment operator =. Here’s an example:

# Replace an element at index 2 with a new value
my_list[2] = 35
 
print(my_list)
# [10, 20, 35, 40, 50]

In this example, we replaced the element at index 2 (which is 30) with the value of 35. After the replacement, the updated list became [10, 20, 35, 40, 50].

You can also replace multiple elements at different indices by repeating this process for each index. We see that in the output, the element at index 2 has been replaced with the new value.

Video, Further Resources & Summary

In this tutorial, we learned how to replace an element at a specific index in a list in Python. By directly assigning a new value to the desired index, we can update the element while keeping the rest of the list intact.
