Changing List Items (Mutability)
Lists are mutable, meaning you can change them after creation.

names = ["Ali", "Sara", "John"]

names[1] = "Nova"
print(names)

['Ali', 'Nova', 'John']

📌 Strings and numbers alone cannot be changed like this, but lists can.

Adding Items to a List

➕ append() — add to the end

numbers = [1, 2, 3]
numbers.append(4)
print(numbers)

Output:

[1, 2, 3, 4]

➕ insert() — add at a specific index

numbers.insert(1, 10)

Result:

[1, 10, 2, 3, 4]

Removing Items from a List

❌ remove() — remove by value

numbers.remove(10)

❌ pop() — remove by index (or last item)

numbers.pop()     # removes last item
numbers.pop(0)    # removes first item

📌 pop() is useful when you want the last added item removed.

Length of a List (len())

To know how many items are in a list:

fruits = ["apple", "banana", "mango"]
print(len(fruits))

Output:

3

This is very useful with loops.

For Today Lets stop here and try these. if you finish these you can go ahead check about looping through lists it will be our tomorrow challenge that we will tackle.
