Python：带有字符串列表和子字典的嵌套字典
Posted
技术标签:
【中文标题】Python：带有字符串列表和子字典的嵌套字典【英文标题】：Python: nested dictionary with string list and subdictionaries 【发布时间】：2021-11-10 11:55:32 【问题描述】：我对某些 YouTube 频道上制作的 cmets（=文本）感兴趣。我已经使用 Google YouTube Data API 抓取了数据。这些数据具有复杂的结构和格式（见下图），我正试图为一个研究项目解开这些数据。
cmets 存储在 Text Display 和 Text Original 字段中，它们属于字典 Snippet，而字典又是字典***评论。 ***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。
我认为我需要对字典进行子集***评论，因为我需要的所有 cmets 和相关信息（见下图）都存储在嵌套字典中。我认为我无法访问字典 Top Level Comment，因为它是列表 Snippet 的一部分。所以我首先尝试对列表片段进行子集化。这就是我卡住的地方。
到目前为止，这是我的代码：
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 进行子集化或转换，但未成功。
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 1
Link no 2
Link no 3Link no 4
Link no 5This link 说 ast.literal.eval 不适用于列表和字典？
那么最后 - 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。
编辑：sample data
【问题讨论】：
分享您从电子管中获得的实际数据和所需的输出（作为文本） @balderman - 你的评论是标准的......我描述了日期，包括数据结构的图片。但是，如果您需要数据进行响应。当然，如果您想通过所有的 和 [] 睁大眼睛，我可以分享数据..... 是的，请 - 将其添加到帖子中（您只能添加 子集），但请确保这些是有效的数据结构 @balderman 数据已上传。非常期待您的想法和解决方案。 :-) 我可以看到输入，但看不到请求的输出。你也可以添加这个吗？保存评论的字段是什么？是textDisplay 吗？

【讨论】：
这只能解决部分问题。我需要所有用红色圈起来的字段。 你不认为你可以从这里拿走吗...？ 代码有效。谢谢。字典列表有点难以转换为 DF，因为经常建议的转换代码都不起作用。始终为 channelId 和视频 ID 引入 NaN。所以花一些时间在谷歌上搜索。 （我通常使用 R，而不是 Python）最后dataDF = pd.DataFrame.from_dict(comments, orient='columns') 成功了 --> 我喜欢为人们提供完整的解决方案，因为我很感谢完整的解决方案，并很好地描述了事情发生的原因。以上是关于Python：带有字符串列表和子字典的嵌套字典的主要内容，如果未能解决你的问题，请参考以下文章
