Distributing programs so that recipients can run them is an ongoing
problem.

Operating systems arenecessarily involved, and since not every recipient
uses the exact same configuration of the exact same version of the exact
same operating system, the means of getting your program installed and
working on their computer will differn significantly.

Web applications are attractive for developers in large part because web
standards are hard-won oases of compatibility across different operating
systems.

It is no accident that operating system vendors (Microsoft, Apple,
Google, etc.) keep trying to carve out attractive incompatible features
and areas of their system, to ensure some applications using those
non-standard features will only run smoothly on the operating system
controlled by that vendor.

Indeed, and toolkits like Tkinter make this refreshingly easy to do in a
way that works across all mainstream operating systems today.

What is not standardised is installation of software for end users.

This is the “bootstrap” problem: a Python program is only useful once
there is a Python interpreter installed and working on the recipient's
system. You still need to get the appropriate version of Python
installed on that recipient's operating system.

You'll need to know your target audience, make decisions about the set
of operating systems you want to support, and build a package for each
one.

Common to all mainstream operating systems? No, installation of software
is one major area that makes operating systems incompatible.


For GNU+Linux systems: Up-to-date Python is easily installed as a
dependency of your package. Target the version(s) of Python you know
your recipients will have, and declare a dependency in the operating
system package you make.

For OS X: There is an old, minimal Python installation, which is
probably too old for you to target. I am not aware of a good dependency
resolution system; you'll need to get the latest stable Python onto the
recipient's system with their help.

For iOS: I'm not aware of a good way to install Python programs on iOS.

For Android: There is a decent dependency system, but again I'm not
aware of a good standard way to have a Python program install onto
Android.

For MS Windows: There is definitely no good dependency resolution system
for you to use. You'll need to bundle a Python interpreter with your
program as a single installable file. This makes your program much
larger and redundant with any other such program on the system; this is
what Microsoft has doomed developers to work with.
