We're going to do some more practice involving functions and variables to make sure you know them well. This exercise should be straight forward for you to type in, break down, and understand.

However, this exercise is a little different. You won't be running it. Instead you will import it into your python and run the functions yourself.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

def break_words(stuff):
	"""This function will break up words for us."""
	words = stuff.split(' ')
	return words
def sort_words(words):
	"""Sorts the words."""
	return sorted(words)
def print_first_word(words):
	"""Prints the first word after popping it off."""
	word = words .pop(0)
	print word
def print_last_word(words):
	"""Prints the last word after popping it off."""
	word = words .pop(-1)
	print word
def sort_sentence(sentence):
	"""Takes in a full sentence and returns the sorted words."""
	words = break_words(sentence )
	return sort_words(words)

def print_first_and_last(sentence):
	"""Prints the first and last words of the sentence."""
	words = break_words(sentence )
	print_first_word(words )
	print_last_word (words )

def print_first_and_last_sorted(sentence):
	"""Sorts the words then prints the first and last one."""
	words = sort_sentence(sentence)
	print_first_word(words )
	print_last_word (words )

First, run this like normal with python ex25.py to find any errors you have made. Once you have found all of the errors you can and fixed them, you will then want to follow the WYSS section to complete the exercise.
