Answer 1

As the name implies, writerows writes rows, not columns. Furthermore, your lists are not equally sized, so you'll need to do something to account for that. The standard way of handling such a thing is using itertools.zip_longest.

from itertools import zip_longest # izip_longest in python2.x

with open("assignment_7_results.csv", "w") as f:
    w = csv.writer(f)
    w.writerow(["Number of Words", "Words/Sentence"])
    for x, y in zip_longest(number_of_words_sentence, mean_word_per_sentence):
        w.writerow([x, y])
