where do my python files go in linux?

[Jorgen Bodde]

Hi All,

I am trying to make a debian package. I am following the tutorial by
Horst Jens (http://showmedo.com/videos/video?nam...romSeriesID=37)
and it is very informative. However one thing my app has and his
doesn't, is multiple python files which need to be executed. For
example

{dir}/app
app.py

app.py calls a lot of modules in {dir}/app. Horst says the python file
goes in /usr/bin/app.py which is ok with me, but I have multiple
python files, and I decided to use an app.sh script to call my python
files. In the /usr/bin I do not see subdirs so I assume that is not
really desirable.

Question 1. Where do I put the bulk of python scripts in a normal
linux environment?
Question 2. Should I use *.pyc rather then *.py files to speed up
executing as the user cannot write to /usr/bin or any other dir in the
system and everytime my app runs it will recompile it

Thanks for any advice or maybe a good tutorial how to set up files in
a linux environment

With regards,
- Jorgen

On a Debian system:
I would put app.py in /usr/local/bin. I would create the directory
/usr/local/lib/app, and put all other *.py and *.pyc files there. At the
top of app.py, I'd add the following line so that I could import files
directly from /usr/local/lib/app:

sys.path.insert(0,'/usr/local/lib/app')
Alternatively, using your app.sh approach, I'd put app.sh in
/usr/local/bin/, and all *.py and *.pyc files in /usr/local/lib/app. I'd
invoke Python something like this:

PYTHONPATH=/usr/local/lib/app:$PYTHONPATH python -m app

(The -m switch searches the Python path for a module to run.)
If it's more of a library than an application (maybe there is a command
line script, but users could want to import the modules directly), then
I'd stick all the modules in /usr/local/lib/python2.x/site-packages, and
the command line scripts in /usr/local/bin.
Yes, install the *.pyc files. I recommend putting *.py files there as
well, so users can refer to it if there are any problems, but you don't
have to. The Python module compileall is your friend here.

Have look at the Debian Python Policy
(should be in /usr/share/doc/python/python-policy.* on
Debian systems)

Rather than re-inventing the wheel, please have a look at distutils:
http://docs.python.org/lib/module-distutils.html

It does most if not all of the things you want to do.
If you want something more advanced, read about eggs.
