Hello, not sure how to complete this python project. If someone could complete and add comments on each step that would be great, thank you.

Modify insertion sort to sorts a list of strings instead of numbers.It shouldn't return anything.The sorting should ignore case.For example"Zebra"should come after"apple","maRker"should come after"marble",etc.Name this function string_sort.The resulting list should contain the exact same strings as the original list,but in sorted order.
