I have started to use the gspread library and have sheet already that I'd like to append after the last row that has data in it. I'll retrieve the values between A1 and maxrows to loop through them and check if they are empty. However, I am unable to add a variable to the second line here. But perhaps I am just not escaping it correct? I bet this is very simple:
maxrows = "A" + str(worksheet.row_count)
cell_list = worksheet.range('A1:A%s') % (maxrows)
