有多少人在通过YouTube接口观看YouTube直播？

import requests

api_key = 'YOUR_API_KEY'
channel_id = 'YOUR_CHANNEL_ID'

url = f'https://www.googleapis.com/youtube/v3/liveBroadcasts?part=snippet,contentDetails,status&channelId={channel_id}&key={api_key}'

response = requests.get(url)
data = response.json()

if 'items' in data:
    for item in data['items']:
        if item['status']['lifeCycleStatus'] == 'live':
            broadcast_id = item['id']
            live_stats_url = f'https://www.googleapis.com/youtube/v3/liveBroadcasts/broadcasts/{broadcast_id}/liveChat?part=snippet&key={api_key}'
            live_stats_response = requests.get(live_stats_url)
            live_stats_data = live_stats_response.json()
            if 'items' in live_stats_data:
                viewer_count = live_stats_data['items'][0]['snippet']['liveChatViewerCount']
                print(f'Current viewers: {viewer_count}')
