I guess I just found the answer to my problem :)

------

from functools import partial

for button in [self.button_1, self.button_2, ..., self.button_0]:
    QtCore.QObject.connect(button, QtCore.SIGNAL('clicked()'),
partial(self.button_clicked, button))

def button_clicked(self, button):
    print "yeah!"

------

works like a charm, and seems elegant enough to me :)

Cheers,
Ruben
