Google drive API download files - python - no files downloaded

Changing from BytesIO to FileIO allowed the file to actually be downloaded. This was the line I modified my code to:

fh = io.FileIO(filename, 'wb')

Here is the complete code that allowed me to download the file:

def download_file(file_id, mimeType, filename):    if "google-apps" in mimeType:        # skip google files        return    request = drive_service.files().get_media(fileId=file_id)    fh = io.FileIO(filename, 'wb')    downloader = MediaIoBaseDownload(fh, request)    done = False    while done is False:        status, done = downloader.next_chunk()        print "Download %d%%." % int(status.progress() * 100)if __name__ == '__main__':    flow = client.flow_from_clientsecrets(      'client_secrets.json',      scope='https://www.googleapis.com/auth/drive.readonly',      redirect_uri='urn:ietf:wg:oauth:2.0:oob')    auth_uri = flow.step1_get_authorize_url()    webbrowser.open(auth_uri)    print auth_uri    auth_code = raw_input('Enter the auth code: ')    credentials = flow.step2_exchange(auth_code)    http_auth = credentials.authorize(httplib2.Http())    drive_service = discovery.build('drive', 'v3', http_auth)    files = drive_service.files().list().execute()    for f in files['files']:        print f['name']        download_file(f['id'], f['mimeType'], f['name'])

The file is downloading, but the example given by google doesn't do anything with the file.

You simply need to return the contents of the BytesIO buffer like this (just adding a return at the end)...

def download_file(service, file_id):    request = 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))    return fh.getvalue()
