Yes. The way to set a class attribute is the same way that you set an
attribute on *any* object:
some_object.attribute_name = something

SWIG supports opaque pointers that you can pass into and out of Python without
any problems.
Working with SWIG isn't that bad for basic stuff, although it can get
complicated if you need to have it interpret exotica like references,
structures, or such for Python. Having a good C++ background

This isn't an answer to your question, but I'm doing about the same in

Hi there,
I've been using C/C++ for many years (python, just reading about it).
I have a software written in C/C++ but considering porting most of it
to python, as it seems like it's a better choice for decision making

My intention is to set a class attribute so that any number of
instantiations will have this value.
the module is tmpl.py. the class is tmpl.
if from the script I do this:
import tmpl
tmpl.tmpl.templatepath = kbLib.templatepath
I get error message:
'module' object has no attribute 'templatepath
hi I faced this problem before and people of tutor helped me to solve it by
only one line
ex.

a.replace(",", " ","[","]","u").split() ## you can put any kind of unicode
that you expect inside the " "

How did the string u"1,2,3,4" get into the database in the first place?
The sqlite3 module offers a mechanism to convert data fro

Hello,
Solved it.
Problem was that I used fileinfo instead of getinfo.
Thanks for the help.
