    Google Spreadsheets Python

    Google Sheets Python API

    ...To access spreadsheets via Google Sheets API you need to authenticate and authorize your application. Older versions of gspread have used oauth2client.

If you familiar with the Jupyter Notebook, Google Colaboratory is probably the easiest way to get started using gspread.
