Getting KeyError: 'viewCount' for using Youtube API in Python

Question

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:

---------------------------------------------------------------------------

---> 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.

Did you try to check what keys are present in the result? Did you try reading the API documentation, in order to understand what should be present? — Karl Knechtel

Did you do a null check? I tested it and its working fine for me if a viewCount is there. — Linda Lawton - DaImTo

As @DalmTo said, it's not impossible that the value of viewCount is null, as far as I remember having worked with it, it can be null or any integer (including 0) — Benjamin Loison

When I'm trying to run the code for a single video, I'm getting the answer. But I want the solution for a list of videos and there are so many videos. — Zaki Gundagi

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.

Views = video['statistics'].get('viewCount')
