[Guidance needed] Python def question

It looks like concat_words is meant to take one parameter, a list, not three parameters as you have it set up.

Take a look at this example, and see if it helps you get there:

words = ['apple', 'orange', 'pear']
for index in range(len(words)):
    print(index, words[index])

Really this should be done with enumerate, but I have a feeling you haven't covered that yet:

words = ['apple', 'orange', 'pear']
for index, word in enumerate(words):
    print(index, word)
