from datetime import date
now = date.today()
now
now.strftime("%m-%d-%y. %d %b %Y is a %A on the %d day of %B.")
# dates support calendar arithmetic
birthday = date(1985, 12, 1)
age = now - birthday
age.days

When I select Run Module in the Edit window, I got only
two >>> after the RESTART line.
I expected to see the output of several commands!
Typing in age.days do produce the number of days.
Why I do not get any output?
Thanks for any guidance.
You never gave it any commands that print output.
I suggest reading the Python tutorial.

The problem with the world is stupidity. Not saying there should be a
capital punishment for stupidity, but why don't we just take the
safety labels off of everything and let the problem solve itself?

while the interactive console echoes the result back if you type in an
arbitrary expression, the interpreter doesn't do that if you run things in
a script.
to print stuff from a script, use the "print" statement.
print now
print now.strftime(...)
...
print age.days
your favourite tutorial (hopefully) contains more information about the
interactive mode, and how it differs from code in scripts or modules.
hope this helps!

To be more specific, when you type in an expression at the Python
prompt, it will evaluate it and then print it (if it doesn't evaluate
to None). In a module it doesn't do that, as then you'd have all sorts
of things printed out modules were imported.

When you run code from an edit window, IDLE saves the file to disk and then
*imports* it into the shell window. If you *paste* code into the shell
window (regardless of where from), then it acts like you typed it and you
will get expression results echoed, as you expected.
I got caught be this at first too, since I have run many snippets by
pasting.
