I apologize for my earlier snide remark as I was not then aware there was an

Someone has posted a pointer to Python code that is supposed to do that. If
that is suitable, the

parentheses to make your intent clear and over-ride it.
But it makes me think of a related question. Assume you are writing code in

I have tried to startup my IDLE python severally but it keeps giving the
following message:
IDLE’s subprocess didn’t make connection. See the ‘Startup Failure’ section of
the IDLE doc online at
https://docs.python.org/3/library/idle.html#startup-failure.
