If want a simple to understand library for Google Spreadsheets, here ya go:
Here is a simple example from the github page:
import gspread # Login with your Google account gc = gspread.login('email@example.com','password') # Open a worksheet from spreadsheet with one shot wks = gc.open("Where is the money Lebowski?").sheet1 wks.update_acell('B2', "it's down there somewhere, let me take another look.")
Nice an easy!
