While the QObject.sender() method should work, it is not thread safe.
The QSignalMapper[1] class seems to do what you want, too, *if* I
understand what you are saying correctly.

Another option would be to create an list of slots, something like:

changeValueSlots = [lambda x: changeValue(x, cb) for cb in comboBoxList]

Then connect each sender to a different slot in that list.
