Hi Emil Hejlesen,

Really close. The challenge requires that you title case the string for the third element of the returned tuple, you've capitalized it - You'll need to use .title() not .capitalize()

Also, I'm not sure why you've added the additional ,), around each element ... you're effectively returning a tuple containing single element tuples (kinda!) ... instead just try: 

    return string.upper(), string.lower(), string.capitalize(), string[::-1]

If you really want to separate the elements, you could use: 

return (string.upper()), (string.lower()), (string.capitalize()), (string[::-1])
# or hardcore/my eyes are burning mode
return ((string.upper()), (string.lower()), (string.capitalize()), (string[::-1]))
# but it isn't necessary and I think makes it harder to read

Great effort though :smile: keep up the good work and happy coding,
Dave :dizzy:

hi dave

it was the .capitalize() that was wrong, i changed it to .title() and the thing with the () was just to try and structure it for me but i didn't help, thank you for the help :)

(('HI THERE',), ('hi there',), ('Hi there',), 'ereht ih')

^ that's some sample output i get with your function. Is that what the challenge wants from you?

Remember that an easy way to make something into a tuple is putting a comma after each item:

bob = 1, 2, 3, 4
# becomes (1, 2, 3, 4)
