About the challenge

This is my code for the challenge: 

def stringcases (string):
    uppercase = string.upper()
    lowercase = string.lower()
    single_word = string.split()
    titlecased = single_word[0]
    for word in single_word[1::]:
        titlecased += " " + word.capitalize()
    temp = single_word[-1::-1]
    reverse = " ".join(temp)
    return (uppercase, lowercase, titlecased, reverse)

but I dont know why they said my reversed case is wrong. I've even tried this one to reverse every letter in a word:

list_of_string = list(string)
temp = list_of_string[-1::-1]
reverse = "".join(temp)

but it still wrong. Can someone help me to resolve this?

Your second version should handle the reversing, but you still have an issue with the title casing. The code here capitalizes each word individually except for the first word. But the challenge is expecting to see every word capitalized. Fix that, and you should pass the challenge.

But be aware that there are easier ways to accomplish both the title casing and the reversing. As the challenge hinted, "There are str methods for all but the last one.", and for the reversing (the "last one"), slices can also be applied directly to strings, you don't need to convert them from/to lists.

actually something to note there with the title casing, is that it's not that his code doesn't capitalize the first word, but it adds a second lower cased copy of the first word in front of the rest that have their first letter capitalized.

or, at least it does if I make a string variable and put a series of words through

Edit: nvm, steven was right about it being the first word getting missed, I just misread the situation when I changed the 

for word in single_word[1::]:

# to 0 instead

for word in single_word[:]:

which just caused it to print capitalized first letters of all my string words, but also left a lower cased version of the first one at the front of the string, leaving me with an extra item for some reason
