Hi,
I have a strange behaviour in my code.

In an interactive session, the result is as expected:

Python 3.4.3 (default, Oct 14 2015, 20:28:29)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> a = None
>>> try:
...     _ = a.value
... except AttributeError:
...     print('OK')
...
OK
>>>

But not in my code:

    def call_settings_dialog(self):
        try:
            _ = self.video.category
            self.core.artelive.configure_downloading(self.video)
        except AttributeError:
            self.core.artetv.configure_downloading(self.video)

and ...

Traceback (most recent call last):
  File "/home/vincent/qarte-3/trunk/loadingscheduler.py", line 240, in 
call_settings_dialog
    _  = self.video.category
AttributeError: 'TVItem' object has no attribute 'category'

I have two types of video, one with an attribute category handled by a 
module 'artelive' and an other without this attribute handled by an 
other module, that's the reason of this code.


... I have just rewrite the line "_ = self.video.category" and the 
problem disappears.
