I would personally write something like this:
class A(QObject):
def __init__(self):
self.counter = 0
Timer.singleShot(100, self.domath())
Slot()
def domath(self):
# do the computation
self.counter += 1
if self.counter != 10:
Timer.singleShot(100, self.domath())
else:
self.counter = 0;
Disclaimer: even though it looks like PyQt code, this is only pseudo code. I have never tested, etc, but the concept is valid in my opinion.
