The loop itself is fine, the issue is with the spacing in your print statement. If you ran the code you have written the result would be:


As you can see it is not spaced properly, that is because of the fact that when you concationate two string together they are merged together without any spacing being added, so if you want proper spacing you have to it on on your own manually. The easiest way of doing this is to add a space at the start of the "world" string like this:

for word in hellos: 
    print(word + " World") 

Changing your loop to look like that will allow you to complete the challenge.
