Ask the people who maintain makefiles whether that's a good thing or
not. HINT: Many will say no.

VSCode runs on Linux. Also, there are easy ways to do the same sort of
thing in many editors that I've used.

(Not sure why you specifically say 2.7, as IDLE for any version of
Python runs on Linux, far as I know.)

I don't understand what any of this has to do with anything. Do you
suspect that your code is fraught with indentation bugs? If so, pretty
much ANY Python-aware editor will help you, as will Python 3.x, as
will Python2 with the "-tt" option.
