In the following cell, we've loaded the text of Pride and Prejudice by Jane Austen, split it into individual words, and stored t

Sever21 [200]

Answer:

Explanation:

Since the array is not provided, I created a Python function that takes in the array and loops through it counting all of the words that are longer than 5. Then it returns the variable longer_than_five. To test this function I created an array of words based on the synapse of Pride and Prejudice. The output can be seen in the attached picture below.

def countWords(p_and_p_words):

longer_than_five = 0

for word in p_and_p_words:

if len(word) > 5:

longer_than_five += 1

return longer_than_five
