Hi friends,
I have a C/C++ application and I wrote a .py file to extend it.
The .py file includes some simple functions without import any other
modules.
Today, I want to update my .py file and import SMTP library in the
file, but it seems fail to import SMTP library.
So I want to ask: when the

Hi to all!
I have a little problem. I want to develop an application in c/c++ that
creates a window with gtk+ accordinly to the information on a xml file.
The funcions that are called for manage the event should be written in
python. I don't know how to do it, can you help me? Is it possible?

Thanks a lot, very clear and usefull anser!
Yes, I know PyGTK and wxPython, but I want to develop a plugin for
another application that requires c++. I guess that embedding is the
appropriate way.
Thanks.

I'd go one step further. Most people expect the first item to correspond
to True and the second one to correspond to False. So:

The answer is simply no, just use an if statement instead.
That's not true.

If your test variable has specific values to branch on, the standard
way is to have those values be keys in a dictionary, and do:
branched_func_obj = dict_of_values.get(testvar)

Python does not have a ternary operator analogous to C's :?. There are

Yeah, that's how I would do it. How many of these things do you have?
