Python: Replace the last element in a list with another list - w3resource
June 28, 2025 - # Define two lists 'num1' and 'num2' containing integers num1 = [1, 3, 5, 7, 9, 10] num2 = [2, 4, 6, 8] # Update the last element of 'num1' (using slicing) to be the entire 'num2' list # This effectively replaces the last element of 'num1' with the elements of 'num2' num1[-1:] = num2 # Print the modified 'num1' list, which now contains the elements of both 'num1' and 'num2' print(num1) ... Write a Python program to replace the last two elements of a list with another list.

>>> array1 = ['A', 'B', 'C', 'D', 'E', 'F']
>>> array2 = ['G', 'H', 'I']
>>> array1 = array1[:-1] + array2
>>> array1
['A', 'B', 'C', 'D', 'E', 'G', 'H', 'I']

To replace parts of a python list, you can use slice assignment:
>>> array1 = ['A', 'B', 'C', 'D', 'E', 'F']
>>> array2 = ['G', 'H', 'I']
>>> array1[-1:] = array2
>>> array1
['A', 'B', 'C', 'D', 'E', 'G', 'H', 'I']
You can use slice assignment to replace any part of a list, including insertion of lists where you do not replace existing elements:
>>> array1[0:0] = ['1st', '2nd']
>>> array1
['1st', '2nd', 'A', 'B', 'C', 'D', 'E', 'G', 'H', 'I']
Here the [0:0] slice selects an empty part of array1 and "replaces" it with the new elements.

Write a Python program to replace last value of tuples in a list
The program is written in Python and it modifies a list of tuples by adding an element to each tuple. Initially, a list · l is created containing 3 tuples, each with 3 elements. The program uses a list comprehension to modify each tuple in the list · l. The list comprehension creates a new list by iterating over the tuples in ... [:-1] to exclude the last element of each tuple.

Use negative index.
Ex:
myList = [[1, 'A1', 100, '1001', '1', '1001', 'None'],
[2, 'B1', 101, '3008', '2', '3008', 'bb'],
[3, 'C1', 102, '607', '3', '607', 'None']]
myList = [i[:-1] + [""] if i[-1] == 'None' else i for i in myList ]
print(myList)
Output:
[[1, 'A1', 100, '1001', '1', '1001', ''],
[2, 'B1', 101, '3008', '2', '3008', 'bb'],
[3, 'C1', 102, '607', '3', '607', '']]

Use negative indexing:
for subList in myList:
if subList[-1] == 'None':
subList[-1] = ' '
myList
# [[1, 'A1', 100, '1001', '1', '1001', ' '],
# [2, 'B1', 101, '3008', '2', '3008', 'bb'],
# [3, 'C1', 102, '607', '3', '607', ' ']]

Replacing Elements in a List (Video) – Real Python
To explore some index assignments, create a list of integers one to seven and call it numbers. 00:59 Now, change the second element to the string "second" using assignment. numbers at index one equals "second". 01:07 Confirm that numbers has updated and the integer two has been replaced with the string "second". Naturally, this works with reverse indexing as well. 01:16 Change the last value in numbers to the string "last", numbers at index negative one equals "last".

Python: Replace Item in List (6 Different Ways) • datagy
August 12, 2022 - How to use for loops and while loops to replace an item in a Python list ... Python lists are ordered, meaning that we can access (and modify) items when we know their index position. Python list indices start at 0 and go all the way to the length of the list minus 1. You can also access items from their negative index. The negative index begins at -1 for the last item and goes from there.

Use list pop along with index assignment
>>> l1 = ['A','B','C','D','E','F']
>>> l2 = ['X' for _ in range(len(l1))]
>>> print(l1)
['A', 'B', 'C', 'D', 'E', 'F']
>>> print(l2)
['X', 'X', 'X', 'X', 'X', 'X']
>>> for idx in range(len(l1)-1):
p = l1.pop()
l2[idx+1] = p
>>> print(l1)
['A']
>>> print(l2)
['X', 'F', 'E', 'D', 'C', 'B']
