Python List Operations

This Python program demonstrates basic list operations, including adding, inserting, extending, removing, sorting, and finding the index of an element in a list.

Features

• Create an empty list.
• Append multiple elements.
• Insert a value at a specific position.
• Extend the list with another list.
• Remove the last element.
• Sort the list in ascending order.
• Find and display the index of a specific element.

How It Works

1. Start with an empty list my_list.
2. Append the values 10, 20, 30, 40.
3. Insert 15 at the second position (index 1).
4. Extend the list with [50, 60, 70].
5. Remove the last element from the list.
6. Sort the list in ascending order.
7. Find the index of 30 and display it.

Example Output

Final list: [10, 15, 20, 30, 40, 50, 60]
Index of 30: 3
