Executing Python code via a shell might produce subtle bugs. See

We're talking about executing the python executable via a shell, not
python code via a "python shell", which is something different.

Seeing the example was not clear, sorry. Just tried to you give a piece of code which would fail doing shell-commend-on-region. Try print(u'\xA9') with python2. With python3 it works here. AFAIU the current python.el doesn't pipe to Python-code to exec through a shell - for related reasons.



Following the OP's suggestion seems reasonable. Just drop it at place
and see if something gets broken - wouldn't expect it.
See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25025#8 for why it
would break.

Only see a question there, not a statement. BTW have no system of the OP's kind, can't check that.
