What is the correct syntax to access the value (the taco's price) that the key "tacos" references in a menu dict?
taco_price = menu[tacos]
taco_price = menu{"tacos"}
taco_price = menu[taco_price]
taco_price = menu["tacos"]
taco_price = menu[tacos]
taco_price = menu{"tacos"}
taco_price = menu[taco_price]
taco_price = menu["tacos"]

How would you update the price of a taco to be 4.50 in a menu dict? Assume the key is the item name and the value is the item's price.
tacos[menu] = 4.50
menu[tacos] = 4.50
menu[4.50] = "tacos"
menu["tacos"] = 4.50
tacos[menu] = 4.50
menu[tacos] = 4.50
menu[4.50] = "tacos"
menu["tacos"] = 4.50
