does not build if python3 less-than 3.6 (e.g. python3.5): SyntaxError: invalid syntax

[sto6]

The usage of f-string requires python3.6. If the found python3 is 3.5 the build fails. My example happens to be on a centos-7, where python3.6 is available (installed) but /usr/bin/python3 is python3.5 due to the requirements of other system on the host.

Is it true: python3.6 (apparently) is now a requirement of the BUILD; but only the BUILD and still no python is required at runtime??

@sto6 : Donn did that. I never use f-strings.

@sto6 : I just modified it so that it will be compatible with any Python-3 revision.

Sorry about that.

That said, every Python version before 3.8 is EOL: https://devguide.python.org/versions/

Confirmed, thanks. Please describe python3 dependency in INSTALL and: http://opencircuitdesign.com/magic/install.html

While you're there, remove 'csh'/'tcsh' (no longer needed)
