The most common way to do things is to tell your users to install
whatever python distribution you pick and then optionally
install these extra packages (if you need any) and then give them a python
program to run.
But you can also package everything up into a .exe for them if they
need this.

For general interest purposes, as you can see, with my posts I
usually include E.D.G. and the date of the posting. This is because the
projects that I work on involve scientific research. And this way printed
versions of the posts can be made. And they will include references that
people can use. The printed versions would not have the types of
information that are included with the electronic newsgroup distributions.
What I was asking about in that earlier post is something that very
few programmers or perhaps even no programmers are familiar with. Most
people know what the .exe versions of programs are. But what I was asking
about is more basic.
It can take a considerable amount of time and effort to get a
programming language installed and running with all of the features that are
needed. It probably took me 5 to 10 years to get Perl organized on my
computer like that.
Once that process is done, people who are not professional
programmers don't want to have to constantly update and change the basic
language they have running on their computers. So, they might do what I do
though I have never heard of anyone else doing that.
My entire Perl language is in a directory called "Perl" on my
computer. I use ActiveState 5.10 Perl which is a very old version. But it
does everything that needs to be done except graphics and fast calculations.
For the graphics I use a Perl to Gnuplot "Pipe" that works quite well and
which took a long time for me to develop. A very old version of Gnuplot is
also used for simplicity. I consists of just 2 small .exe files.
Then if I want to run a .pl program on any computer or even from a
flash drive I simply copy the entire 5.10 Perl directory to the new computer
or flash drive. And any Perl program will then run on the new computer or
from the flash drive.
Windows let you specify that a .pl program should always be opened
with perl.exe. The same is probably true with Python. So, Perl itself does
not actually need to be installed on a computer to get .pl programs to run.
However, it is probably a good idea to do that so that the perl.exe address
is in the right Windows Environment variables.
So, that is what I was asking about Python. Once it is installed and
running properly, can people simply copy the entire Python directory to some
other computer or flash drive and a Python language program will then run?
If necessary, to get Perl programs to run faster we were planning to
use a Perl to Fortran "Pipe" plus file storage of bulk data. Fortran would
then process the files and tell the Perl program when it was done. But
before doing that we decided to see if we could find another language that
would do everything that my version of Perl does plus graphics and fast
calculations. It appears that Python will do that. But it also appears
that it would take quite a while to select a specific version of Python and
then learn how to get everything organized and running.
Another of my posts will probably go into more detail regarding that
subject.
Thanks for the comments.

E.D.G.
