如何使用python检查youtube视频是否存在？

import requests

def check_youtube_video(video_id):
    api_key = 'YOUR_YOUTUBE_API_KEY'
    url = f'https://www.googleapis.com/youtube/v3/videos?id={video_id}&key={api_key}&part=snippet'
    
    response = requests.get(url)
    data = response.json()
    
    if 'items' in data and len(data['items']) > 0:
        return True
    else:
        return False

# 调用示例
video_id = 'YOUR_YOUTUBE_VIDEO_ID'
exists = check_youtube_video(video_id)
if exists:
    print('视频存在')
else:
    print('视频不存在')
