如何附加＆＃x27; null＆＃x27;或＆＃x27; n/a＆＃x27;从YouTube API提取数据时的价值

Question

我的代码允许从YouTube API调用数据，并将其列入列表以形成数据FRAM。 但是，当API无法访问“项目”时，它会返回错误。为了避免错误，我需要附加“ n/a”或“ null”，并在API无法访问某些项目时通过。

def get_channel_stats(youtube, channel_ids):
all_data = []
for i in range(0, len(channel_ids), 50):
    request = youtube.channels().list(
                part='snippet,contentDetails,statistics',
                id = ','.join(channel_ids[i:i+50]))
    response = request.execute()

    for i in range(len(response['items'])):
        data = dict(channel_name = response['items'][i]['snippet']['title'],
                    published_date = response['items'][i]['snippet']['publishedAt'],
                    subscribers = response['items'][i]['statistics']['subscriberCount'],
                    views = response['items'][i]['statistics']['viewCount'],
                    total_videos = response['items'][i]['statistics']['videoCount'],
                    playlist_id = response['items'][i]['contentDetails']['relatedPlaylists']['uploads'],
                    retrieved_date = date.today().strftime('%Y/%m/%d')              
                    )
        
        all_data.append(data)
return all_data

任何指示或建议都会非常有帮助。

谢谢您。

请让我知道这是否有效：

def get_channel_stats(youtube, channel_ids):
    all_data = []
    for i in range(0, len(channel_ids), 50):
        request = youtube.channels().list(
                part='snippet,contentDetails,statistics',
                id = ','.join(channel_ids[i:i+50]))
        response = request.execute()
        
    if resp.items:
        for i in range(len(response['items'])):
            data = dict(channel_name = response['items'][i]['snippet']['title'],
                        published_date = response['items'][i]['snippet']['publishedAt'],
                        subscribers = response['items'][i]['statistics']['subscriberCount'],
                        views = response['items'][i]['statistics']['viewCount'],
                        total_videos = response['items'][i]['statistics']['videoCount'],
                        playlist_id = response['items'][i]['contentDetails']['relatedPlaylists']['loads'],
                        retrieved_date = date.today().strftime('%Y/%m/%d')              
                        )
            
            all_data.append(data)
    else:
        all_data.append('n/a')
    
    return all_data

我要做的就是检查request.execute（）的JSON是否具有称为items的东西;如果确实如此，我继续进行您的循环，如果没有，我将'n/a'附加到all_data list。
