Traceback (most recent call last):
File "python", line 9, in
File "python", line 6, in join_strings
AttributeError: 'str' object has no attribute 'append'
Replace this line with your code. n = ["Michael", "Lieberman"] # Add your function here def join_strings(words): result = "" for i in range(len(words)): result.append(i) return result print join_strings(n)
