Thanks for the documentation reference. Can we at least add this link reference [1] as a note or something like that into those documentation sections: [2] https://docs.python.org/2/library/stdtypes.html#string-formatting and  [3] https://docs.python.org/3/library/string.html#string-formatting

I couldn't fine the printf specific documentation at first, so this is why I created the report.

Regards,
Jerry
