Stringcases - Can't see what I've done wrong?

Hey

My code below works, at least in the way I interpret the question, but I get the error

"Bummer! Didn't get back all of the right cases"

Looking at other questions on this, seems people are using slices and beacuse of that I can already see a better way of doing it, but don't know why this method isn't accepted?

Could someone please show me where it's wrong?

Thank you!

stringcases.py 
def stringcases(arg1):
    my_list = []
    my_list.append(arg1.upper())
    my_list.append(arg1.lower())
    my_list.append(arg1.capitalize())

    backwards = []
    for letter in arg1:
        backwards.insert(0, letter)

    reverse = ''.join(backwards)
    my_list.append(reverse)

    my_tuple = tuple(my_list)

    return(my_tuple)

You are using the capitalize function, however the challenge expected you to use the title function.

I'm pretending that I'm in the Python Shell

>>> "abc".capitalize()
"Abc"
>>> "abc".title()
"Abc"
>>> # Over here you might be wondering the differences, to find out the differences just read on...
>>> "abc abc".capitalize()
"Abc abc"
>>> "abc abc".title()
"Abc Abc"

I hope this demonstrates the difference. :smile:

I hope this helps! ~Alex

By the way, you look like a great Python programmer so far! If you'd like a little challenge, check this out! :smile:
