# Inserting an item at a specific index

# Clearing the list

# Extending the list with another list
my_list.extend([5, 6, 7])  # Adds all elements from the provided list

# Slicing the list (getting a subset of the list)
sliced_list = my_list[1:5]  # Gets elements from index 1 to index 4
print("Sliced list:", sliced_list)  # Output: [2, 3, 4, 5]

# Reversing the list
