Replace Integer in List in Python (Example)

In this tutorial, you’ll learn how to replace an integer 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 integer values. We’ll explore different examples to demonstrate this process.

The table of contents is structured as follows:

Let’s get started!

Initializing Sample List

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

# Initializing a sample list
my_list = [1, 2, 3, 4, 5]

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

Example: Replacing an Integer Value

To replace an integer value in the list, we can iterate over each element and use conditional statements to identify the integer value we want to replace. Here’s an example where we replace the value 3 with 10:

# Replace 3 with 10
for i in range(len(my_list)):
    if my_list[i] == 3:
        my_list[i] = 10

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 equal to 3. If it is, we replace it with 10.

After executing this code, the updated list will be [1, 2, 10, 4, 5]. Let’s print the final list:

print(my_list)  # [1, 2, 10, 4, 5]

As you can see, the integer value 3 has been replaced with 10 in the list.

In this tutorial, we explored an example of how to replace an integer value 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 integer values.
