What is the expected output?

What is the expected output for the objective?

Without spoiling the correct code, could someone please give me an example of what the expected output is for: stringcases('heLLo There').

Thank you, much appreciated!

On a (related) side note, perhaps it would be worthwhile to include example output as part of the objectives - as CodeWars does.

stringcases.py 
def stringcases(txt):
    """
    (str) -> tuple

    From txt, return a tuple of different string formats:
    all uppercase, all lowercase, titlecasted, and reversed.

    >>> stringcases('heLLo There')
    ('HELLO THERE', 'hello there', 'Hello There', 'ereht olleh')
    """

    txt_list = []

    txt_list.append(txt.upper())

    txt_list.append(txt.lower())

    txt_list.append(txt.title())

    reverse_txt = ''

    len_count = 0
    index_count = -1

    while len_count < len(txt):
        reverse_txt += txt[index_count]
        len_count += 1
        index_count -= 1

    txt_list.append(reverse_list)

    print(tuple(txt_list)

The example you've written in your docstring is correct:

('HELLO THERE', 'hello there', 'Hello There', 'ereht olleh')

Thanks Stuart!

I am able to get the expected output with the above code, any idea why it's not passing?

Note, to reverse the txt, I have removed the while loop and using the far simpler: txt_list.append(txt[::-1])

Is the problem simply that you are printing rather than returning your list of tuples? The rest looks good to me.

Ah, how silly of me. Now works fine. Thanks again :)
