Python 3: Dict понимание с помощью if else и добавление в список

0 голосов
/ 19 февраля 2019

У меня есть список словарей следующей структуры: 

myList=[{"ID": someString, "sequence": someString2, "quality":[5,6,7]},{...,'quality':[55,66,77]},...]

Качество имеет список чисел в качестве значения.Первое число представляет качество в позиции 0, второе в позиции 1 и т. Д.

Я хочу создать словарь качества для позиции следующей структуры: 

qualityDict={0:[5,55], 1:[6,66],2:[7,77] etc}

myИдея: 

qualityDict={}
for entryDict in myList:
        qualityDict={pos:[entryDict['quality'][pos]] if pos not in qualityDict.keys() else qualityDict[pos].append(entryDict['quality'][pos]) for pos in range(0,len(entryDict['quality']))}

QualityDict создается как словарь pos: [value] для каждого pos в диапазоне (0, длина текущего качества).Если ключ еще не присутствует в dict, он установлен и значение установлено, если он присутствует, я хочу добавить к значению.

Итак, после первой итерации, например, у меня естьДикт с 0,1,2,3 .... длина первого качества (которое было повторено) в качестве ключей, и каждый ключ имеет список с одним значением.Во второй итерации я хочу добавить текущее качество к списку существующего значения.

Я получаю сообщение об ошибке для добавляющейся части: у объекта 'NoneType' нет атрибута append

Чтоя скучаю?Спасибо:)

Я сделал предположение о том, как выглядит ваша структура данных.

Код ниже: 

myList = [{'ID': 'someString', 'sequence': 'someString2', "quality": [5, 6, 7]},
          {'ID': 'someString1', 'sequence33': 'someString21', "quality": [52, 64, 77]},
          {'ID': 'someString13', 'sequenc3e': 'someString213', "quality": [532, 634, 
         737]}]

qualityDict = {idx: val['quality'] for idx, val in enumerate(myList)}
print(qualityDict)

Вывод: 

{0: [5, 6, 7], 1: [52, 64, 77], 2: [532, 634, 737]}

Вывод (на основе обновленного «myList»):

Я бы сделал это с collections.defaultdict.Он не будет использовать dict-понимания, но будет выглядеть так: 

from collections import defaultdict

myList = [...]  # as you described
qualityDict = defaultdict(list)

for entryDict in myList:
    for indx, qualNum in enumerate(entryDict['quality']):
        qualityDict[indx].append(qualNum)

Чтобы сделать это с помощью dict-понимания, вы можете сделать отдельный qualityDict для каждой записи в myList, а затем объединить ихкаким-то образом (но это, вероятно, потребует больше кодирования).

Редактировать: путь с пониманием dict

Как я уже говорил ранее, самый простой способ сделать это с пониманием dictбыло бы сделать отдельный qualityDict для каждой записи, а затем объединить их как-то.Т.е. 

myList = [...] # as before
qualityDicts = []

# each entry gets a separate quality dict
for entryDict in myList:
    qualityDicts.append(
        {indx: qualNum for indx,qualNum in enumerate(entryDict['quality'])
    )

# now combine, not sure of a pretty way to do it with dict comprehensions
qualityDict = {}
for qdict in qualityDicts:
    for indx, qNum in qdict.items():
        qualityDict[indx] = qualityDict.get(indx, []) + [qNum]
...
