Hi, I'm not so sure that's true. I have a large 900 line program where
some original plot code just continues beyond plot() and show(), after
the user closes the plot window. New code that I put in gets knotted up,
as far as I can tell. In both cases, I've put print statements after
show(), but nothing appears in the shell or, if run by clicking the
program file, in the DOS-like window that appears.
Further, I posted this elsewhere, and someone claims to have tried a few
simple examples with show() at the ended,and they did not get tied up in
knots when the user closed the window. I'm going to assume he used IDLE,
or a straight execute of the file.

The basic problem is the show(). One person checked out the examples I

The behavior that you describe, is the normal behavior of Matplotlib: When you
call show(), the program gets stuck.
Therefore the call to show is always the last statement in the example
programs. Show returns when the last plot window is closed, and in principle
the program could then continue.
If you want to look at plots while the program is running, you must use
Ipython. This is a modified Python interpreter, that contains special code to
change the way how Matplotlib works.
