This is the error message: Oops, try again. join__strings(['x', 'y', 'z', 'a']) returned ['', 'x', 'y', 'z', 'a'] instead of 'xyza'
I do not see what has gone wrong with my code to create ['', 'x', 'y', 'z', 'a'] instead of "xyza" like expected.
Any clarification would be appreciated.
Thank you in advance.
def join_strings(words): result = [""] for word in words: result.append(word) return result
