您可以使用google-api-client lib 访问数据，简单示例：
from apiclient.discovery import build
from apiclient.errors import HttpError
from oauth2client.tools import argparser
# Set DEVELOPER_KEY to the API key value from the APIs & auth > Registered apps
# tab of
# https://cloud.google.com/console
# Please ensure that you have enabled the YouTube Data API for your project.
DEVELOPER_KEY = key
YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"
def youtube_search(vid):
youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION,
developerKey=DEVELOPER_KEY)
# Call the search.list method to retrieve results matching the specified
# query term.
search_response = youtube.search().list(
part="snippet",
relatedToVideoId=vid,
type="video",
).execute()
print(search_response)
print(search_response)
try:
youtube_search("KQEOBZLx-Z8")
except HttpError as e:
print "An HTTP error %d occurred:\n%s" % (e.resp.status, e.content)
有效参数在here 中列出，下面是另一个完整示例。您需要启用 youtube 数据 api 并拥有 开发者密钥。
使用请求：
import requests
url = "https://www.googleapis.com/youtube/v3/videos?part=snippet&id={id}&key={api_key}"
_id = "KQEOBZLx-Z8"
r = requests.get(url.format(id=_id, api_key=DEVELOPER_KEY))
print(r.json())
这给了你：

获取title和categoryId：
r = requests.get(url.format(id=_id, api_key=DEVELOPER_KEY))
js = r.json()
items = js["items"][0]
print (items["snippet"]["categoryId"])
print (items["snippet"]["title"])
输出：
1
12 Days of Christmas | Christmas Carols by Hooplakidz
这将允许您以编程方式完成所有操作，创建 id 到类别名称的映射：
import requests
def get_data(key, region, *ids):
url = "https://www.googleapis.com/youtube/v3/videos?part=snippet&id={ids}&key={api_key}"
r = requests.get(url.format(ids=",".join(ids), api_key=key))
js = r.json()
items = js["items"]
cat_js = requests.get("https://www.googleapis.com/youtube/v3/videoCategories?part=snippet®ionCode={}&key={}".format(region,
key)).json()
categories = {d['id']: d["snippet"]['title'] for d in cat_js["items"]}
for item in items:
yield item["snippet"]["title"], categories[item["snippet"]["categoryId"]]
如果我们通过传入 he required args 来运行它，我们会得到：
In [86]: for title, cat in get_data(DEVELOPER_KEY, "IE", "KQEOBZLx-Z8", "ALTc-Cqz650"):
....: print(title, cat)
