Organizing our module into functions

Let's organize our words module using functions.

First we'll move all the code except the import statement into a function called fetch_words(). You do that simply by adding the def statement and indenting the code below it by one extra level:

from urllib.request import urlopen


def fetch_words():
   with urlopen('http://sixty-north.com/c/t.txt') as story:
       story_words = []
       for line in story:
           line_words = line.decode('utf-8').split()
           for word in line_words:
           story_words.append(word)

 for word in story_words:
 print(word)

Save the module, and reload the module using a fresh Python REPL:
