我试图运行Python代码来使用YouTube生成的API密钥来下载YouTube数据。我的问题是每当我尝试运行代码时,我都会收到警告和错误。当我从Coursera下载代码时,该代码曾经工作过一次,但是现在一旦它停止工作,我就得到了结果。获取YouTube数据API的关键错误和Python代码导入错误
此代码的输出是一个CSV文件,其中包含像like count,view count,comment count dislike count,favorite count等视频数据,稍后我将使用它来对R或Python做一些统计分析,作为我的Coursera课程。
PFB这是我使用的代码:xxxxx是对我来说这是我从谷歌的YouTube数据API V3所产生的API密钥

每当我运行代码,我得到以下错误:
观看次数= video_result [u'statistics'] [ “观看次数”]
KeyError异常: '统计'
警告:googleapiclient.discovery_cache:在使用oauth2client> 4.0.0时file_cache不可用 回溯(最近呼叫最后一次): 文件“C:\ Anaconda3 \ Anaconda3 4.2.0 \ lib \ site-packages \ googleapiclient \ discovery_cache__init__ py”为,从google.appengine.api进口的memcache线36,在自动检测 导入错误:没有名为模块‘谷歌’
在处理上述异常,另一个异常:

如何克服这个问题?
我试过video_result..get('Statistics'),但它没有得到我所需的结果。代码提前1-2次运行,没有任何变化,当我下载它时给了我25个视频结果(正如你可以在底部看到可以提取的结果的最大限度,我已将它们设置为25),但由于某些原因,它现在停止工作。 – SidM
