Are my descriptions (comments) correct here? [newbie needs help]

I'm curious what the name of the "slots" are that I mentioned in my comments. These are slots in the function. There are two in the parentheses in this function.

This is from an exercise in learn python the hard way.

#This line defines the function cheese_and_crackers and it assigns two "slots" which have 
#distinct names that can be used by other pieces of code to correspond to the two variables
#in the strings in this function.
def cheese_and_crackers(cheese_count, boxes_of_crackers):
#This line is the first string printed by this function and it takes the first variable in any
#piece of code that calls this function.
	print "You have %d cheeses!" % cheese_count
#This line is a string which takes input from a variable at the part where it says "%d"
	print "You have %d boxes of crackers!" % boxes_of_crackers
#This line is another string from the function cheese_and_crackers.
	print "Man that's enough for a party!"
#This line is a string which is the last printed element of the function cheese_and_crackers.
	print "get a blanket.\n"
	
#This prints a line above the standard output from the function cheese_and_crackers.
print "We can just give the function numbers directly:"
#This line calls the function and inputs 20 and 30 into the respective "slots" (two of them)
#in this function. Maybe these are called arguments?
cheese_and_crackers(20, 30)

#This line prints on top of the output from the function cheese_and_crackers when it takes the
#input from "amount_of_cheese" and "amount_of_crackers"
print "OR, we can use variables from our script:"
#This line defines the variable "amount_of_cheese" as 10
amount_of_cheese = 10
#this line defines the variable amount_of_crackers as 50
amount_of_crackers = 50
#This line takes the variables amount_of_cheese and amount_of_crackers and plugs them into the 
#function cheese_and_crackers defined at the start
cheese_and_crackers(amount_of_cheese,amount_of_crackers)

#This line prints a "new" statement above the output of cheese_and_crackers function output
print "We can even do math inside too:"
#This line calls the function cheese and crackers from the top and it inserts the value of the
#combined numbers and uses each as a variable as seen in the defined function's 2 variable set up
#Then each value is printed in the designated spot in the function cheese_and_crackers
cheese_and_crackers(10 + 20, 5 + 6)

#This line prints a "new" statement above the output of cheese_and_crackers function output
print "And we can combine the two, variables and math:"
#This line calls the function cheese and crackers from the top and it inserts the value of the
#variables in the parentheses and combines them with the numbers seen next to them and it plugs
#the result into the strings (and variables) stipulated in the function cheese_and_crackers
cheese_and_crackers(amount_of_cheese + 100, amount_of_crackers + 1000)
