I am having the same issue with 'hello world'.

Thank you, though, I have to ask the question again; how do I pass the first test if my result is the same as the 'Expected'

Expected: "h e l l o w o r l d", instead got: "h e l l o w o r l d"

and yet it still fails. Need this be so cryptic?

Read the examples and follow that; CW parses the messages and often removes extra spaces, so don't trust the messages much in this case.

same here. cant solve it... tests are wrong?

Hi, thanks for your reply. I put in a space because I had tried it with and without (I did hash it out - I'm yet to refactor), both versions did not pass the first example and yet the second test passes with this code.
What is also confusing about the description is that it shows the spacified 'hello world' with a space, 'h e l l o w o r l d'. The test example, however, asks for 'h e l l o w o r l d', without a space. Here is the error message I'm getting from the failed first example. Which one is correct?

Test.assert_equals(spacify("hello world"),"h e l l o  w o r l d")

or

Expected: "h e l l o w o r l d", instead got: "h e l l o w o r l d"

Unfortunately, I can't identify the difference between these two.

Very thankful for your help and sorry for calling an issue.

Please, do not put "issue" if you think it might be just your code (which is the case, I would say).

What are you using space for, for example?

Well, strictly speaking, shouldn't you have a question mark after this sentence?
