It looks like you are using the wrong string method.

For the third value, the challenge said to capitalize the "first letter of each word". But the "capitalize" method only affects the first letter of the first word.

You might want to check the documentation on string methods. I'll bet you can find another method that will do what you want. :wink:

Oh ok, thank you :) I will find that :) have a great day and thanks for your time.

Yeah man :) I appreciate you ... the title method was a bit tricky, but I found that in 5 minutes :)

How come this is wrong:

def stringcases(str1): str_upper= str1.upper() str_lower=str1.lower() str_titled=str1.title() temp=[] str_list=str1.split(" ") str_reverse_list = str.join(["{} ".format(str_list[-(i+1)]) for i in range(len(str_list))]) tupple_string_list = (str_upper, str_lower, str_titled, str_reverse_list) print(tupple_string_list)

stringcases("abcd efghijk lmnopqr stuvwxyz")

answer: ('ABCD EFGHIJK LMNOPQR STUVWXYZ', 'abcd efghijk lmnopqr stuvwxyz', 'Abcd Efghijk Lmnopqr Stuvwxyz', 'stuvwxyz lmnopqr efghijk abcd ')

This is what is asked in the question. Can anyone verify this code, I will appreciate it.

You're working too hard! The challenge doesn't ask you to reverse the order of the words in the string, just reverse the entire string. This can be done in a single statement using a slice.

But good job on implementing a much more complicated process! :+1:
