Que. 1: Explain List Data Type and it’s methods with suitable
example. (10 Marks)
What is a List?
In Python, a List is a built-in data type used to store multiple items in a
single variable. Lists are created using square brackets [].
Key Features:
Ordered: Items have a defined order that will not change.
Mutable: You can change, add, or remove items after the list is
created.
Allows Duplicates: Lists can have two items with the same value.
Common List Methods
1. append(): Adds an element at the end of the list.
2. insert(): Adds an element at a specific position.
3. remove(): Removes the first item with the specified value.
4. pop(): Removes the element at a specific position (or the last one if
not specified).
5. sort(): Sorts the list in ascending order.
Example Code:
# Creating a list
fruits = ["apple", "banana", "cherry"]
# 1. append() - adding mango
fruits.append("mango")
# 2. insert() - adding orange at index 1
fruits.insert(1, "orange")
# 3. remove() - removing apple
