Functions may have been a mind-blowing amount of information, but do not worry. Just keep doing these exercises and going through your checklist from the last exercise and you will eventually get it.

There is one tiny point though that you might not have realized which we'll reinforce right now: The variables in your function are not connected to the variables in your script. Here's an exercise to get you thinking about this:

#!/usr/bin/env python# -*- coding: utf-8 -*-def cheese_and_crackers(cheese_count, boxes_of_crackers):	print "You have %d cheeses!" % cheese_count	print "You have %d boxes of crackers!" % boxes_of_crackers	print "Man that's enough for a party!"	print "Get a blanket.\n"	print "We can just give the function numbers directly:"cheese_and_crackers (20 , 30)print "OR, we can use variables from our script:"amount_of_cheese = 10amount_of_crackers = 50cheese_and_crackers (amount_of_cheese, amount_of_crackers)print "We can even do math inside too:"cheese_and_crackers (10 + 20, 5 + 6)print "And we can combine the two, variables and math:"cheese_and_crackers (amount_of_cheese + 100 ,amount_of_crackers + 1000)

result：

This shows all different ways we're able to give our function cheese_and_crackers the values it needs to print them. We can give it straight numbers. We can give it variables. We can give it math. We can even combine math and variables. 

In a way, the arguments to a function are kind of like our = character when we make a variable. In fact, if you can use ‘=’ to name something, you can usually pass it to a function as an argument.
