Iterating over dictionary and list items in a nestled for loop
Question:
How do I make it so the for loop statement is actually iterating (in order) over all the items in the list? (My best attempt below)
e.g
• Ham & Cheese (Hc) $5.00
Marinara tomato sauce
• Cheesy Garlic (Cg) $5.00
Served with garlicky aioli
menu = {"Pizzas" : {("Hc", "Ham & Cheese") : 5, ("Cg", "Cheesy Garlic") : 5, ("H", "Hawaiian") : 5, ("Cc", "Classic Cheese") : 5, ("Cv", "Classic Veggie") : 5,
("M", "Margherita") : 8.50,("Hs", "Hot & Spicy Veggie") : 8.50, ("P", "Pepperoni") : 8.50, ("Ml", "Meat Lovers") : 8.50,
("Bc","Buffalo Chicken") : 8.50, ("Cs", "Chicken Supreme") : 8.50,("Bb", "Beyond Beef") : 8.50},
"Sides" : {("Cf", "Crinkle-Cut Fries") : 5.50,("Gb","Garlic Bread") : 4.49, ("Ct", "Chicken Tenders") : 8.99},
"Drinks" : {("Co", "Coca Cola (1.5L)") : 4.79, ("S", "Sprite (1.5L)") : 4.79,("P", "Pump (750ml)") : 3.50, ("Ko", "Keri Orange Juice (350ml)") : 2.99}}
food_desc = ["Marinara tomato sauce", "Served with garlicky aioli", "Loaded with mozzarella cheese", "Stretchy, gooey sauce.",
"Juicy pineapple", "Freshly chopped tomatoes", "Our explosive combination of jalapenos", "Meltingly delicious mozzarella",
"With a variety of meats", "Loaded with our ", "Over juicy chicken breast", "Covered with loads",
"Perfectly seasoned", "Fresh from the oven", "Flavorful chicken wings"]
def show_menu():
print("Menu:n".center(60))
print("Pizzas n")
for (code, food), price in menu["Pizzas"].items():
print(f" • {food :<30} {'('+ code + ')': <10} ${price:.2f}")
for description in food_desc:
continue
print(f"{description} n")
show_menu()
(Sorry, my code is really messy)
Answers:
This should give you enough to work with, check out the zip function.
for ((code, food), price), desc in zip(menu['Pizzas'].items(), food_desc):
print(code, food, price, desc)
Output:
Hc Ham & Cheese 5 Marinara tomato sauce
Cg Cheesy Garlic 5 Served with garlicky aioli
H Hawaiian 5 Loaded with mozzarella cheese
Cc Classic Cheese 5 Stretchy, gooey sauce.
Cv Classic Veggie 5 Juicy pineapple
M Margherita 8.5 Freshly chopped tomatoes
Hs Hot & Spicy Veggie 8.5 Our explosive combination of jalapenos
P Pepperoni 8.5 Meltingly delicious mozzarella
Ml Meat Lovers 8.5 With a variety of meats
Bc Buffalo Chicken 8.5 Loaded with our
Cs Chicken Supreme 8.5 Over juicy chicken breast
Bb Beyond Beef 8.5 Covered with loads
As a suggestion, I might consider restructuring your data like so:
food_iter = iter(food_desc)
menu = {category:{code:{'name':food,
'price':value,
'desc':next(food_iter) if category == 'Pizzas' else None
}
for (code, food), value in info.items()}
for category, info in menu.items()}
Output:
