我们已经讨论了播放列表的前两种方法 – 列出与频道 ID 关联的所有播放列表，检索我的播放列表，即授权用户帐户的播放列表。
现在，我们将讨论另外三种方法：插入播放列表、更新播放列表和删除播放列表。这意味着我们可以只使用 API 插入，或者我们可以说创建一个新的播放列表，然后我们可以只使用 API 将视频上传到播放列表，或者我们可以对视频进行评级以将其添加到所需的播放列表。
现在我们可以通过查看事物如何相互关联以及如何使用 API 完成所有操作来推导出相关性。您只需要一组有效的凭据来授权访问。所有这些方法都需要用户授权，所以我们将首先讨论如何创建OAuth Credential ，然后我们将看看这些功能的实现。
按照以下步骤生成客户端 ID 和密钥。
- 转到 Google Google Developers Console，然后单击页面右上角的登录。使用有效 Google 帐户的凭据登录。如果您没有 google 帐户，请先设置一个帐户，然后使用详细信息在 Google Developers 主页上登录。
- 现在导航到开发人员仪表板并创建一个新项目。
- 单击启用 API 选项。
- 在搜索字段中，搜索Youtube Data API并选择下拉列表中的 Youtube Data API 选项。
- 您将被重定向到显示有关 Youtube Data API 信息的屏幕，以及两个选项： ENABLE 和 TRY API 。
- 单击启用选项以开始使用 API。
- 在 APIs & Services 下的侧边栏中，选择Credentials 。
- 在页面顶部，选择OAuth 同意屏幕选项卡。选择一个电子邮件地址，如果尚未设置，请输入产品名称，然后单击保存按钮。
- 在凭据选项卡中，选择创建凭据下拉列表，然后选择OAuth 客户端 ID 。 OAuth 通常用于需要授权的情况，例如检索用户喜欢的视频。
- 选择其他应用程序类型，输入名称“YouTube Data API Myvideos”，然后单击“创建”按钮并单击“确定”。
- 单击客户端 ID 右侧的下载按钮以下载 JSON 文件。
- 将文件保存并重命名为 client_secret.json 并将其移动到工作目录。
使用 pip命令安装其他库：
pip install --upgrade google-auth google-auth-oauthlib google-auth-httplib2插入播放列表的代码：此示例显示如何在授权用户的帐户中插入/创建播放列表。 snippet.title是创建新播放列表时的必需属性。其他的是可选的。

当您执行代码时，系统会要求您提供授权代码。要获取代码，您需要按照以下行上方的命令提示符屏幕中提到的链接进行操作：输入授权代码。 
现在点击链接并复制粘贴您将通过授予权限获得的授权代码。 
从上面的输出中，您可以看到我的帐户中有一个新的播放列表，其标题和描述与代码中提到的相同，但没有添加视频。
我们可以根据您的选择通过代码或从 youtube 手动将视频添加到播放列表中，或者您也可以对视频进行评分以将其添加到播放列表中。
注意：您可以从可用的库菜单中查看您拥有的播放列表列表，方法是单击您初始的 youtube 页面右上角的图标，然后转到第一个选项注册的电子邮件 ID。这将在最左侧的垂直菜单中显示库选项。库列出了您帐户中的所有播放列表。
更新播放列表的代码：此示例向您展示了如何更新播放列表属性，如标题、说明或隐私状态。 id和snippet.title是强制性属性，所有其他属性都是可选的。
