This is interesting, isn't it?

You probably know more also about this programming language
than you express here.

I suggest to take another look at information from the section
“2.4.3. Formatted string literals”.
https://docs.python.org/3/reference/lexical_analysis.html#f-strings
This software documentation provides the information “New in version 3.6”.
Will such a detail trigger any more software development consequences?
Regards,
Markus

Thanks foor this information. Denis, would it be possible to express the

Which is the last revision of the Python programming language
that you would like to support so far?
