i need to figure out a math code for the adding of pizza's and delivery charge.
Where it says "print (("Thank you") , Contact ,".")" it don't seem to work.
And also make a loop in it so the customer can cancel the order at anytime, and restarts it or just quit (deleting what ever the customer has put in.

Okay, there are several things to fix here.

First, you're defining two functions, hi() and hi2(), neither of which actually do anything. If you want your code to be part of the functions, you need to indent it. Also, remove the pass.

Second, on line 29, you try to assign a value to D/P. You can't do that. A variable name can't have '/' in it.

Third, on line 52 you have the following:

elif Pizza != 'D' or 'P':

You can't do it like that, because 'P' will always evaluate to True. You need to either do something like this:

elif Pizza != 'D' or Pizze != 'P':

...or change line 47 to say elif rather than if, and then change line 52 to say:

else:

For adding the pizza prices together... well, how are you expecting the input to be formatted? You'll need to find the prices of each pizza and add them together, but for that you need to know what input you'll recieve.

how come this one works then?

Here, I didn't completely finish the program, just wrote it to get it working somewhat like you wanted and hopefully help you out. Ask me questions if you're confused or whatever.

pizza_d = {
1 : ("Apricot Chicken $13.50"),
2 :(/>"Meat Lovers $13.50") ,
3 : ("Vegetarian $13.50") ,
4 : ("Double Cheese $13.50"),
5 : ("Hawaiian $13.50"),
6 : ("Pepperoni $8.50"),
7 : ("Beef and Onion $8.50"),
8 : ("Ham and Cheese $8.50"),
9 : ("Tomato Margherita $8.50"),
10 : ("Classic Italian $8.50"),
11 : ("BBQ Chicken and Bacon $8.50"),
12 : ("Italian Veg $8.50")
}
while 1:
	while 1:
		try:
			num_pizzas = int(raw_input('How many pizzas do you want to order?'))
			break
		except ValueError:print ("invalid choice")
	#show_menu()
	x = 1 
	pizzas=[]
	prices=[]
	buf = []
	while x<= num_pizzas:
		while 1:
			try:
				pizza = int(raw_input("Which pizza do you want to order?"))
				if pizza in pizza_d: 
					pizzas.append(pizza_d[pizza])
					buf = pizzas[x-1].split('$')
					prices.append(buf.pop())
					break
				else: continue
			except ValueError: 
				print ("invalid choice")
				continue
		x+=1
	#add total 
	total = 0
	for price in prices:
		total += float(price)
		
	#still need to add errorchecking to make sure d or p was entered
	d_or_p = raw_input('Delivery or Pickup?')
	d_or_p.lower()
	if d_or_p == 'd' or d_or_p == 'delivery':
		#do stuff for delivery
		total+=3.0
		print "you ordered ", len(pizzas), "pizzas:"
		for pizza in pizzas:
			print pizza
		print "your total is $", total
	elif d_or_p == 'p' or d_or_p == 'pickup':
		print "you ordered", len(pizzas),"pizzas:"
		for pizza in pizzas:
			print pizza
		print "your total is $", total
		
	

Edit: Your code above is working because it's all valid and everything. The point is that your functions aren't doing anything other than taking up space because the pass is there, which is just a space filler for when you have to have a function do something but don't want it to do anything. Anyways, good luck man and have a nice night/day.
