Что я сделал, вместо того, чтобы использовать словарь, я использую список для передачи данных в новую функцию.
Текстовый файл -> Список -> Dict -> Список -> sortedList
Вот моя новая функция fileReader:
def fileReader(filename):
"""
Take the given txt file and format into proper list for boxes and items
:param filename: The filename of the text file
:return: Send lists to to be used by an algo.
"""
with open(filename, 'r') as myFile: # Open the correct file
itemList = []
boxList = []
myList = [line.split() for line in myFile.readlines()]
boxLine = ' '.join(myList[0])
for line in range(1, len(myList)):
lines = ''.join(myList[line])
itemName = lines[:-1]
weight = lines[len(lines) - 1:]
item = InventoryItem(itemName, int(weight))
itemList.append(item)
boxString = ""
count = 0
for char in boxLine:
if char != " ":
boxString = boxString + char
else:
boxName = "Box" + str(count)
box = BoxInventory(boxName, int(boxString), int(boxString))
boxList.append(box)
boxString = ""
count += 1
Затем я читаю и сортирую данные в каждом алгоритме, используя тот же метод:
def roomiest(myReturnDict):
"""
For each item find the box with the greatest remaining allowed weight that can support the item and place the item in that box
:param boxList: The list of boxes in the class from the given file
:param itemList: The list of items in the class from the given file
:return: If boxes were able to fit all items(1); items in box with individual weights(2); Box name with max
weight(3); items with their weights that were left behind(4)
"""
itemData = list(myReturnDict.get("itemList"))
boxData = list(myReturnDict.get("boxList"))
sortedItemList = sorted(itemData, key=lambda x: x.weight, reverse=True)
sortedBoxList = sorted(boxData, key=lambda x: x.remainingWeight, reverse=True)
myReturn = {}
myReturn['boxList'] = boxList
myReturn['itemList'] = itemList
return myReturn
Мои классы данных выглядят следующим образом:
@dataclass
class InventoryItem:
name: str
weight: float
@dataclass
class BoxInventory:
name: str
maxWeight: float
remainingWeight: float
contents: dict = ""
def itemWeight(item):
print("Weight of", item.name, "is: ", item.weight, "\n")
return item.weight
def remainWeight(box):
print("Rem. weight in ", box.name, "is: ", box.remainingWeight, "\n")
return box.remainingWeight
