How can I reverse a section of a list using a loop in Python?

Question

I\'m in need of a little help reversing a section of a list in Python using a loop.

I have a list: mylist = [\'a\', \'b\', \'c\', \'d\', \'e\', \'

You can try this. This makes use of no slicing, and can use either a while loop or for loop.

    def reversed_list(my_list, index):
        result = []
        list_copy = my_list.copy()

        i = 0
        while i < index+1:
            result.append(my_list[i])
            list_copy.remove(my_list[i])
            i+=1

        result.reverse()

        return result + list_copy

Or with a for loop

    def reversed_list(my_list, index):
        result = []
        list_copy = my_list.copy()

        for i in range(len(my_list)):
            if i < index + 1:
                result.append(my_list[i])
                list_copy.remove(my_list[i])

        result.reverse()

        return result + list_copy
