2,988 Pointswhat does the 'reversed version of the string' looks like? Isn't [uoy sevol esuoheerT] work?
reverse = ''.join(reversed(string.strip(' '))) not match
# Handy functions:
# .upper() - uppercases a string
# .lower() - lowercases a string
# .title() - titlecases a string
# There is no function to reverse a string.
# Maybe you can do it with a slice?

Have you tried something like :
def stringcases(string):
a = string.upper()
b = string.lower()
c = string.title()
d = string[::-1]
tup = a, b, c, d
return tup

But you still have a bit more work to do to satisfy the challenge. You still need to create a function, and the function must return a tuple that includes a lower case, upper case and title case version of the string as well as the reversed one.
And while the iterator reversed function does work, the challenge's suggestion of using a slice ("string[::1]
") is more compact and doesn't need a join.

2,988 PointsMaybe I made some misunderstand on this challenge, but I've tried several functions print ''.join(list(reversed(string[::1]))) ->uoy sevol esuoheert print list(reversed(string[::1])) ->['u', 'o', 'y', ' ', 's', 'e', 'v', 'o', 'l', ' ', 'e', 's', 'u', 'o', 'h', 'e', 'e', 'r', 't'] print ''.join(reversed(string.strip(' '))) ->uoy sevol esuoheert
But I still can't match the requirement of the task -> Create a function named stringcases that takes a string and returns a tuple of four versions of the string: uppercased, lowercased, titlecased (where every word's first letter is capitalized), and [a reversed version of the string].
what does the [a reversed version of the string] would be

2,988 PointsHi Julien,
I've tried your code string[::-1] -> 'uoY sevoL esuoheerT' it seems to be the similar result with mine ''.join(reversed(string.strip(' '))) -> 'uoY sevoL esuoheerT'
for string = 'Treehouse Loves You'
but somehow mine can't pass the challenge, but your solution is correct for this task, thanks :)
