There is nothing exceptional about exceptions in Python. McDonc does a
good job at explaining how to think about exceptions as less than
exceptional:

The only arguably exceptional part is that ideally the ORM would raise

imports don't usually take up too much memory. I'd guess that even
importing a very large number of modules isn't going to grow your
process size by more than 10 MB.
imports are only evaluated once. So if you nest the import into a
view, your process will be smaller until the first time that view
Yes, how many times have you followed the practice of:

2. (re)start dev server and/or update dev database

Presumably you already have all of the data required to generate a
chart on the server? If so, then store the chart data in a model, and
just reference it by id. e.g.
(or w/ a pretty URL: )
And create a Chart object and store it before sending out the HTML
response. Then update your chart view
__dict__ is an attribute of every Python object. It's typically only
an internal detail, and generally not accessed directly. One area
where __dict__ modification would differ from attribute access is with
an attribute that's a property. Modifying the __dict__ would ignore
the property getter/sett

You have to distinguish between "archi
The __file__ attribute of a module can be used as a starting point for
getting at data files within a python package. However, packages can
be installed in zipped format, so if you need to account for this you
can use the pkg_resources module in setuptools:

I think there are two issues at play here:
1. Separate your site or application into multiple Python projects to
promote re-usability, maintainability, extensibility.
2. Place your packages within a top-level package to prevent
namespace collisions to increase re-usability.

I haven't used any of them with Django, but for managing Zope, Plone

Try using the subprocess module (Python 2.4+) to call your program instead
of os.
