How do I slice lists in Python in a memory-efficient way?

Slicing lists in Python is an essential skill that allows you to access and manipulate parts of lists efficiently. When you slice a list, you create a new list containing only the elements you want, rather than modifying the original list. This approach is memory efficient since Python optimizes memory usage for slices.

For example, if you have a list of numbers and want to get a portion of it, you can use slicing syntax:


    numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
    sliced_numbers = numbers[2:5]  # Gets elements from index 2 to 4
    print(sliced_numbers)  # Output: [3, 4, 5]
