Python lists are versatile data structures that allow you to store and manipulate collections of items.

In this article, we’ll dive into the world of list manipulation by gaining a solid understanding of modifying, adding, and removing elements from lists.

Modifying Elements in a List

Modifying individual elements in a list is a fundamental operation. We’ll explore how to access and modify list elements using indexing and assignment.

fruits = ['apple', 'banana', 'cherry']
fruits[1] = 'orange'
print(fruits)  # Output: ['apple', 'orange', 'cherry']

First, we create a list of fruits with three elements: ‘apple’, ‘banana’, and ‘cherry’. By accessing the element at index 1 (fruits[1]), we can modify it by assigning a new value ('orange'). The modified list is then printed, showing the updated element at index 1.

Inserting Elements into a List

Inserting elements into specific positions in a list provides flexibility. We’ll demonstrate how to use the insert() method to add an element at a specific index.

colors = ['red', 'blue', 'green']
colors.insert(1…
