   Assumptions:
     * You have one script - script.py, using two additional module - 
module1.py & module2.py.
     * You want to hold the script in some generic Utility folder (on 
your system path or wherever). Let's refer to that folder as 
'D:\Utility', just to make it seem more realistic.
     * Target machine already has the desired Python environment installed.


   The simplest 'all in one' solution would be to simply copy script.py, 
module1.py & module2.py into the 'D:\Utility' folder. Then you can run 
script.py as a script (using whatever Python environment you prefer) and 
its folder (i.e. 'D:\Utility') will automatically be added to the Python 
path, ergo module1.py & module2.py can be easily imported using 'import 
module1' & 'import module2' respectively.

   One possible bad side to this organization is that the user does not 
necessarily know what module1.py & module2.py files are - they are 
stored together with other utility scripts but need not be runnable 
scripts by themselves. If they can be run as standalone scripts then 
that is all fine and well but if they are not - user does now know that 
they should not be and possibly what they are related to.


   A slight variation making it clear which scripts should be runnable 
directly and which should not would be to move module1.py & module.py 
under some 'D:\Utility\script_details' folder and add an empty 
__init__.py file to that folder as well.

   Then module1.py & module2.py can be imported as:
     'import script_details.module1'
   and:
     'import script_details.module2'
   respectively.


   Another addition is to prepare a packaged installer that installs your
files in one of the aforementioned structures as any other application, 
e.g. under '/usr/bin', 'C:\Program Files' or whatever, but that's 
strictly an addition to what was described earlier.


   If the script and the modules you mention are self-contained and are 
not intended to be reused elsewhere, then I don't think you need 
anything more complex than that. If they are not then you have an option 
to place the implementation module in some shared Python environment 
folder, e.g. a specific Python environment's 'site-packages' folder. 
That would allow you to easily reuse those modules from other scripts 
located in other folders, but it would also introduce additional 
complications - with it you need to make sure the folder you placed them 
on has indeed been configured to be located on the used Python 
environment's Python path.


   Another variation is to package an installer that basically installs 
a stand-alone Python distribution together with your script, e.g. like 
something done by cx_Freeze or similar projects. Then your target 
machine does not need to have Python installed separately, but on the 
other hand, the installation is much larger and you risk getting 
multiple Python installations all over the same machine. :-)


   Hope this helps.
