I'm stuck on exercise 16, using strings in lists and functions
It doesn't return what I expect it too, this is the error
Oops, try again. join_strings(['x', 'y', 'z', 'a']) returned '' instead of 'xyza'
I expect it to join the two words together
n = ["Michael", "Lieberman"] def join_strings(words): result= "" for i in range(len(words)): print words.append(result) return result print join_strings(n).
