I don't know if this is just me being stupid, but this seems like a bug
n = ["Michael", "Lieberman"] # Add your function here def join_strings(words): result = " " for i in range(len(words)): result += words[i] return result print join_strings(n)
And it tells me this: Oops, try again.
join_strings(['x', 'y', 'z', 'a']) returned ' xyza' instead of 'xyza'
If this ain't a bug and just my code is wrong, please tell me how to fix it
