How To Change Position Of Element In List Python

Changing the position of an element in a list is a common programming task in Python. It’s a simple yet powerful tool to manipulate lists and reorganize data in a way that fits our needs.

In this tutorial, we will guide you through the steps of changing the position of an element in a list in Python. We will show you how to move an item from one index to another and reorder the entire list based on a specific criterion.

Steps:

1. Create a list

The first step is to create a list in Python. For this tutorial, we will use a simple list of numbers:

2. Move an item from one index to another

To move an item from one index to another, we can use the built-in method pop() followed by insert(). The pop() method removes the element at a specific index and returns it, while the insert() method adds the element back to the list at a different index.

For example, let’s move the first element in the list to the third index:

The resulting list is:

[7, 9, 3, 2, 4, 1]

3. Reorder the list based on a specific criterion

To reorder the list based on a specific criterion, we can use the built-in method sort(). The sort() method sorts the list in ascending order by default, but we can provide a specific function to customize the order.

For example, let’s sort the list in descending order:

The resulting list is:

[9, 7, 4, 3, 2, 1]

Conclusion:

Changing the position of an element in a list in Python is a simple yet powerful tool that can help you manipulate lists and reorder data. By using the built-in methods pop(), insert(), and sort(), you can easily move items to different indices and reorder the list based on your criteria.
