Print list, with values from another list

Question

Sorry if the question is worded awkwardly. What I'm tyring to do:

I have a list.

standardpizzalist = ["1. Supreme", "2. Godfather", "3. Meatlovers", "4. Capricosa", "5. BBQ Chicken", "6. Prawn Delight", "7. Basil and Pork",]

The customer has this list displayed, they then enter which selections they want, eg. 1, 3, 5 would represent Supreme, Meatlovers and BBQ Chicken. These values are saved in a list also:

orderedpizzas = [1, 3, 5]

I need the list orderedpizzas to be displayed on screen, but instead of 1, 3 and 5 being printed, I need it to read the values from the other list. eg. 1. Supreme, 3. Meatlovers, 5. BBQ Chicken.

Do you mean something like this:

>>> for pizza in orderedpizzas: print standardpizzalist[pizza-1] 1. Supreme 3. Meatlovers 5. BBQ Chicken

I think you're better off using a dictionary instead:

>>> pizza_dict {1: 'Supreme', 2: 'Godfather', 3: 'Meatlovers', 4: 'Capricosa', 5: 'BBQ Chicken', 6: 'Prawn Delight', 7: 'Basil and Pork'} >>> pizza_dict[1] 'Supreme' >>> pizza_dict[3] 'Meatlovers' >>> pizza_dict[5] 'BBQ Chicken'

And then we can use a list comprehension to get the names:

>>> ordered_pizzas = [1,3,5] >>> names = [pizza_dict[num] for num in ordered_pizzas] >>> names ['Supreme', 'Meatlovers', 'BBQ Chicken']

print ', '.join(standardpizzalist[x-1] for x in orderedpizzas)

Will give you a comma separated list of ordered pizzas.

Use an ordered dictionary.

from collections import OrderedDict pizzas = OrderedDict() pizzas[1] = 'Supreme' pizzas[2] = 'Godfather' ...etc...

So then when you iterate over the items, the ordering is kept(unlike a regular dict):

for index, pizza in pizzas.items(): print pizza # First prints 'Supreme', then 'Godfather', etc...
