获取 KeyError：“viewCount”用于在 Python 中使用 Youtube API
我正在尝试获取某个频道的视频列表的观看次数。我已经编写了一个函数，当我尝试仅使用“video_id”、“title”和“”来运行它时“发布日期”我得到输出。但是，当我想要查看次数或 API 统计部分的任何内容时，它会给出关键错误。
这是代码：
def get_video_details(youtube, video_ids):
all_video_stats = []
for i in range(0, len(video_ids), 50):
request = youtube.videos().list(
part='snippet,statistics',
id = ','.join(video_ids[i:i+50]))
response = request.execute()
for video in response['items']:
video_stats = dict(
Video_id = video['id'],
Title = video['snippet']['title'],
Published_date = video['snippet']['publishedAt'],
Views = video['statistics']['viewCount'])
all_video_stats.append(video_stats)
return all_video_stats
get_video_details(youtube, video_ids)
这是错误消息：
---------------------------------------------------------------------------
KeyError Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_18748/3337790216.py in <module>
----> 1 get_video_details(youtube, video_ids)
~\AppData\Local\Temp/ipykernel_18748/1715852978.py in get_video_details(youtube, video_ids)
14 Title = video['snippet']['title'],
15 Published_date = video['snippet']['publishedAt'],
---> 16 Views = video['statistics']['viewCount'])
17
18 all_video_stats.append(video_stats)
KeyError: 'viewCount'
我引用了这个 Youtube 视频来编写我的代码。
提前致谢。
I'm trying to get the view count for a list of videos from a channel. I've written a function and when I try to run it with just 'video_id', 'title' & 'published date' I get the output. However, when I want the view count or anything from statistics part of API, then it is giving a Key Error.
Here's the code:
def get_video_details(youtube, video_ids):
all_video_stats = []
for i in range(0, len(video_ids), 50):
request = youtube.videos().list(
part='snippet,statistics',
id = ','.join(video_ids[i:i+50]))
response = request.execute()
for video in response['items']:
video_stats = dict(
Video_id = video['id'],
Title = video['snippet']['title'],
Published_date = video['snippet']['publishedAt'],
Views = video['statistics']['viewCount'])
all_video_stats.append(video_stats)
return all_video_stats
get_video_details(youtube, video_ids)
And this is the error message:
---------------------------------------------------------------------------
KeyError Traceback (most recent call last)
~\AppData\Local\Temp/ipykernel_18748/3337790216.py in <module>
----> 1 get_video_details(youtube, video_ids)
~\AppData\Local\Temp/ipykernel_18748/1715852978.py in get_video_details(youtube, video_ids)
14 Title = video['snippet']['title'],
15 Published_date = video['snippet']['publishedAt'],
---> 16 Views = video['statistics']['viewCount'])
17
18 all_video_stats.append(video_stats)
KeyError: 'viewCount'
I was referencing this Youtube video to write my code.
Thanks in advance.

我得到了它。
我必须使用 .get() 来避免 KeyErrors。对于 KeyErrors，它将返回 None。
替换此代码以获得解决方案。
I got it.
I had to use .get() to avoid the KeyErrors. It will return None for KeyErrors.
Replaced this code to get the solution.
