[PyQt] question about SIGNAL strings

[Zoltan Szalai]

hello,

running the attached code snippet the result is as follows:
2destroyed(QObject*)
2aSignal()

i'd like to ask what are those '2'-s at the start of the strings for?
the result is the same if i'd just print out SIGNAL('aSignal()').
probably a stupid question but i'd like to understand how things work.

PyQt version: 4.7.3
Qt version: 4.6.2
Python version: 2.6.5

thx
Zoltan
