ファイルをダウンロードするGoogleドライブのpython

Question

googledriveからファイルをダウンロードするにはどうすればよいですか？

私はこのリンクを使用してpydriveを使用しています。

#https://drive.google.com/open?id=DWADADDSASWADSCDAW 
    from pydrive.auth import GoogleAuth 
from pydrive.drive import GoogleDrive 

gauth = GoogleAuth() 
drive = GoogleDrive(gauth) 

gdrive_file = drive.CreateFile({'id': 'id=DWADADDSASWADSCDAW'}) 
gdrive_file.GetContentFile('DWADSDCXZCDWA.zip') # Download content file.

documentationで提供されているサンプルコードを試してみてください。ここで

The Drive API allows you to download files that are stored in Google Drive. Also, you can download exported versions of Google Documents (Documents, Spreadsheets, Presentations, etc.) in formats that your app can handle. Drive also supports providing users direct access to a file via the URL in the webViewLink property.

がcode snippetです：

file_id = '0BwwA4oUTeiV1UVNwOHItT0xfa2M' 
request = drive_service.files().get_media(fileId=file_id) 
fh = io.BytesIO() 
downloader = MediaIoBaseDownload(fh, request) 
done = False 
while done is False: 
    status, done = downloader.next_chunk() 
    print "Download %d%%." % int(status.progress() * 100)
