Python - Move Element to End of the List

Last Updated : 30 Jan, 2025

We are given a list we need to move particular element to end to the list. For example, we are given a list a=[1,2,3,4,5] we need to move element 3 at the end of the list so that output list becomes [1, 2, 4, 5, 3].

Using `remove()` and `append()`

We can remove the element from its current position and then append it to the end of list.

Python

a = [1, 2, 3, 4, 5]
ele = 3

a.remove(ele)  # Remove the element
a.append(ele)  # Append it to the end

print(a)

Output

[1, 2, 4, 5, 3]

Explanation:

remove(ele) method removes the first occurrence of the element 3 from the list a.
append(ele) method adds the element 3 to the end of list so the final list becomes [1, 2, 4, 5, 3].

Using `pop()` and `append()`

We can use pop() to remove the element by its value or index and then append it to the end.

Python

a = [1, 2, 3, 4, 5]
ele = 3

a.pop(a.index(ele))  # Remove the element by index
a.append(ele)  # Append it to the end

print(a)

Output

[1, 2, 4, 5, 3]

Explanation:

pop(a.index(ele)) method finds the index of the element 3 using a.index(ele) and removes it from list a by using pop(index).
append(ele) method adds the element 3 to the end of the list, so the final list becomes [1, 2, 4, 5, 3]

Using List Comprehension

This method uses list comprehension to recreate list moving the element to end.

Python

a = [1, 2, 3, 4, 5]
ele = 3

a = [x for x in a if x != ele] + [ele]  # Move element to the end

print(a)

Output

[1, 2, 4, 5, 3]

Explanation:

List comprehension [x for x in a if x != ele] creates a new list with all elements of a except for 3.
Expression + [ele] adds element 3 to the end of the new list, resulting in [1, 2, 4, 5, 3]

Using `index()`

We can find element's index and use slicing to create a new list placing the element at end.

Python

a = [1, 2, 3, 4, 5]
ele = 3

idx = a.index(ele)  # Find the index of the element
a = a[:idx] + a[idx+1:] + [ele]  # Use slicing to place the element at the end

print(a)

Output

[1, 2, 4, 5, 3]

Explanation:

a.index(ele) method finds the index of element 3 in the list a.
Expression a[:idx] + a[idx+1:] + [ele] uses slicing to create a new list excluding the element 3 from its original position and then appending it to end of list.

Move One List Element to Another List - Python

The task of moving one list element to another in Python involves locating a specific element in the source list, removing it, and inserting it into the target list at a desired position. For example, if a = [4, 5, 6, 7, 3, 8] and b = [7, 6, 3, 8, 10, 12], moving 10 from b to index 4 in a results in

We are given a list we need to find the negative index of that element. For example, we are having a list li = [10, 20, 30, 40, 50] and the given element is 30 we need to fin the negative index of it so that given output should be -3.Using index()index() method in Python searches for the first occur

Python - Append given number with every element of the list

In Python, lists are flexible data structures that allow us to store multiple values in a single variable. Often, we may encounter situations where we need to modify each element of a list by appending a given number to it. Given a list and a number, write a Python program to append the number with
