Python - このリストを辞書に変更するには

Question

私は最初の "pts"を取り除き、2をlocとptsのキーとして使い、imsize、loc、pts、imsizeはその値のキーです。

これは私のリストです：

test = [{'pts': u"""{"2": {"loc": [11, 12, 13, 14, 15, 16, 17, 18, 19, 20,

私はこれを試してみました：あなたはここにキーを使用する必要があるとして

 test = test[0] 
     a = test[0].pts 

     print test 
     print a #not print a 

Answer 1

あなたが試す解析できる辞書へのポイントの値を変更する場合：

points = eval(test[0]['pts']) 

これはとpointsが同じようになります：

{'47': {'loc': [34, 35, 36], 
     'pts': [[1393.0609259457722, 1700.979369842461], [1193.01805808595, 1746.23496945665], [957.5577644411103, 1801.984621155289]],

     'imsize': [3264, 2448]} 
} 

points['47']、points['2']、またはpoints['43']の各キーを使用して、各ディクテーションを取得することができます。

Answer 2

代わり

print test[0]['pts'] 

を試してみてください。

Answer 3

あなたが尋ねていることは少し不明だと思います。

辞書のリストがあり、リストの最初の要素（キーがpts）だけが気になるようです。次に、辞書のキーで何かをしたい。辞書のキーはJSON文字列であるため、デコードする必要があります。始めるために、次のことを試してみてください。

from pprint import pprint 
import json 

test = [{'pts': u"""{"2": {"loc": [11, 12, 13, 14, 15, 16, 17, 18, 19, 20,
