I want to thank you for your job and what you make available for the public! 

Please let my say, that there seams to be a little mistake in the PDF-Files you offered for download this night: In the ZIP-File "https://docs.python.org/3.7/archives/python-3.7.2-docs-pdf-a4.zip" there are PDF-Files in the Letter-Format as well - instead of A4-Format! 

With kind regards from Tübingen in Southern Germany, 

Heinrich Ottinger
