前言

Google drive根目录下存在大量文件（数万同类型文件），手动删除极其耗时，同时连接Google drive需要科学上网，一旦断线就需要重新刷新。所以，介绍一种采用google colab读取Google drive内容，并管理文件的方法。

步骤

打开 https://colab.research.google.com/notebooks/ google colab直连google谷歌各个服务，所以无须担心速度稳定性。

• 登录google账号（与Google Drive一致），新建文档

• 输入Python代码如下，并执行等待（来源和修改自https://colab.research.google.com/notebooks/io.ipynb#scrollTo=7taylj9wpsA2）：

  # Import PyDrive and associated libraries.
  # This only needs to be done once per notebook.
  from pydrive.auth import GoogleAuth
  from pydrive.drive import GoogleDrive
  from google.colab import auth
  from oauth2client.client import GoogleCredentials
  
  # Authenticate and create the PyDrive client.
  # This only needs to be done once per notebook.
  auth.authenticate_user()
  gauth = GoogleAuth()
  gauth.credentials = GoogleCredentials.get_application_default()
  drive = GoogleDrive(gauth)
  
  # List .txt files in the root.
  #
  # Search query reference:
  # https://developers.google.com/drive/v2/web/search-parameters
  listed = drive.ListFile({'q': "title contains '.txt' and 'root' in parents"}).GetList()
  for file in listed:
    file.Delete()

  上面代码中’.txt’可以修改为其他类型或者其他搜索条件，具体参考官方举例

• 检查Google drive文件是否被删除，pydrive好像无法长期运行，大概30mins
