Need help on Stringcases program. Computer says Bummer! got the wrong string(s)

When I run the program in workspace it returns a tuple of all types of string required but program calls me Bummer and doesn't like what I wrote. Could you please help?

stringcases.py 
def stringcases(string_value):
    upcase_string = string_value.upper()
    lowcase_string = string_value.lower()
    titlecase_string = string_value.capitalize()
    reverse_string = ''
    x = list(enumerate(string_value))
    x.reverse()

    for item in x:
        reverse_string = reverse_string + item[1]
    return upcase_string, lowcase_string, titlecase_string, reverse_string

The reason your program isn't working is because string_value.capitalize() only capitalizes the first letter of the first word in a string, so you fail the Title cased condition. For title case use string_value.title().

This should work for you:

def stringcases(string_value):
    upcase_string = string_value.upper()
    lowcase_string = string_value.lower()

    # title() used to capitalize every word of a string
    titlecase_string = string_value.title()

    # simplified way to reverse a string in python
    reverse_string = string_value[::-1]

    return upcase_string, lowcase_string, titlecase_string, reverse_string

Everything in your code works, but the 'Titlecased' (first letter of each word is capitalized) needs to use the .title() string method. This will allow you to pass the challenge.

Capitalize only does the first word in a sentence. Where Title does the first letter of every word in the string.

x = 'the chicken laid eggs'
print x.capitalize()
'The chicken laid eggs'
print x.title()
'The Chicken Laid Eggs'
