sorry it was totally bottom of my first message :

others IDE can handle this case) .

now I realyze that my question has not a lot to do with python
language itself and I should resubmit that probably on pydev forums/..

but as I told I wanted to have some advises on the "good" (or not) use
of this "way of doing" with python itself.  You already explained me
it's not the best so far.. and I agree although during (my) dev it
helps ;) (but I do this only with very few classes that have lot of
attributes/methods ofcourse).
