Python: 带有字符串列表和子字典的嵌套字典
Python: nested dictionary with string list and subdictionaries
我对某些 YouTube 频道上的评论（=文本）感兴趣。我已经使用 Google YouTube 数据 API 抓取了数据。数据采用复杂的结构和格式（见下图），我正试图为一个研究项目理清这些数据。
评论存储在 Text Display 和 Text Original 字段中，属于字典 Snippet，它又是词典 顶级评论 的一部分。 顶级评论 是字符串列表的一部分，而字符串列表又是字典 items.
的一部分
我想我需要对字典 顶级评论 进行子集化，因为我需要的所有评论和相关信息（见下图）都存储在嵌套字典中。我不认为我可以访问字典 顶级评论，因为它是列表 Snippet 的一部分。所以我首先尝试对列表 Snippet 进行子集化。这就是我卡住的地方。
这里是我的代码：
from googleapiclient.discovery import build
api_key = '_______________________________'
youtube = build('youtube', 'v3', developerKey = api_key)
#find channel ID https://commentpicker.com/youtube-channel-id.php
request = youtube.commentThreads().list(
part = 'snippet',
allThreadsRelatedToChannelId = 'UC_zxivooFdvF4uuBosUnJxQ'
)
response3 = request.execute()
##Code to explore data structure and format is excluded
#subset dictionary according to keys we want
includedKeys = ['items']
dataDic = {k:v for k, v in response3.items() if k in includedKeys}
在下面的代码中，我尝试以不同的方式对列表 Snipet 进行子集化或对其进行转换，但没有成功。
dataDic2 = {x['snippet'] for x in dataDic} #Link no 1
#TypeError: string indices must be integers
dataDic2 = {x['snippet'] for x in dataDic} #Link no 1
#TypeError: string indices must be integers
dataDic2 = [{'snippet': d['snippet']} for d in dataDic] #Link no 2
#TypeError: string indices must be integers
dataDic2 = [topLevelComment['snippet'] for topLevelComment in dataDic['topLevelComment']['snippet']] #Link no 3
#KeyError: 'topLevelComment'import ast
result = ast.literal_eval('[snippet]')
assert type(result) is list #Link no 4 and 5
#ValueError: malformed node or string: <_ast.Name object at 0x0000010F6D7B9A08>
Link no 3
This link 说 ast.literal.eval 不适用于列表和字典？
最后 - 如何检索数据？
我需要在显示数据结构的图片中用红色圈出的所有字段。

我对某些 YouTube 频道上的评论（=文本）感兴趣。我已经使用 Google YouTube 数据 API 抓取了数据。数据采用复杂的结构和格式（见下图），我正试图为一个研究项目理清这些数据。
评论存储在 Text Display 和 Text Original 字段中，属于字典 Snippet，它又是词典 顶级评论 的一部分。 顶级评论 是字符串列表的一部分，而字符串列表又是字典 items.
的一部分我想我需要对字典 顶级评论 进行子集化，因为我需要的所有评论和相关信息（见下图）都存储在嵌套字典中。我不认为我可以访问字典 顶级评论，因为它是列表 Snippet 的一部分。所以我首先尝试对列表 Snippet 进行子集化。这就是我卡住的地方。
这里是我的代码：
from googleapiclient.discovery import build
api_key = '_______________________________'
youtube = build('youtube', 'v3', developerKey = api_key)
#find channel ID https://commentpicker.com/youtube-channel-id.php
request = youtube.commentThreads().list(
part = 'snippet',
allThreadsRelatedToChannelId = 'UC_zxivooFdvF4uuBosUnJxQ'
)
response3 = request.execute()
##Code to explore data structure and format is excluded
#subset dictionary according to keys we want
includedKeys = ['items']
dataDic = {k:v for k, v in response3.items() if k in includedKeys}
在下面的代码中，我尝试以不同的方式对列表 Snipet 进行子集化或对其进行转换，但没有成功。
dataDic2 = {x['snippet'] for x in dataDic} #Link no 1
#TypeError: string indices must be integers
dataDic2 = {x['snippet'] for x in dataDic} #Link no 1
#TypeError: string indices must be integers
dataDic2 = [{'snippet': d['snippet']} for d in dataDic] #Link no 2
#TypeError: string indices must be integers
dataDic2 = [topLevelComment['snippet'] for topLevelComment in dataDic['topLevelComment']['snippet']] #Link no 3
#KeyError: 'topLevelComment'import ast
result = ast.literal_eval('[snippet]')
assert type(result) is list #Link no 4 and 5
#ValueError: malformed node or string: <_ast.Name object at 0x0000010F6D7B9A08>
This link 说 ast.literal.eval 不适用于列表和字典？
最后 - 如何检索数据？
我需要在显示数据结构的图片中用红色圈出的所有字段。
