How do I close only one specific Excel workbook?

Question

I have two opened workbooks. Workbooks are opened manually not in COM! So I don't have already existing object to close. Workbooks.Open can't help with that and gives me an error. How do I close specific workbook in python which was opened manually by mouse?

from win32com.client import Dispatch
excel = Dispatch("Excel.Application")
excel.Visible = False

excel.DisplayAlerts = False

excel.Workbooks('1.xlsx').Close()
excel.Quit()

Found this VBA stuff and the Python bindings are pretty similar:

from win32com.client import Dispatch

xl = Dispatch('Excel.Application')
xl.Workbooks("FILENAME.EXT").Close(SaveChanges=True)

This totally works for me in Python 3.6, just thought I´d leave that here for others who stumble upon this via Google.
