How to copy .db files from Google Drive?

Question

Python

How can I copy .db files from google drive that are created according to the sqlite3 structure. I write code in Python.

the code

file_db = open('DataBaseUserID.db', 'rb')
file_db.close()
gauth = GoogleAuth()
auth_url = gauth.CommandLineAuth()
drive = GoogleDrive(gauth)
file_list = drive.ListFile({'q': "path_folder in parents and trashed=false"}).GetList()
file_obj = drive.CreateFile({'id': file_list[0]['id']})
file_obj.Trash()
file_obj = drive.CreateFile({'title': 'DataBaseUserID.db', 'mimeType': 'text/txt',
                                     "parents": [
                                         {"kind": "drive#fileLink", "id": path_folder}]})
file_obj.SetContentFile('DataBaseUserID.db')
file_obj.Upload()

ps where path_dolder stands, in my code there is a path to a folder in google drive as text, so don't complain about it
