PyQt: How to dynamically call objectNames?

Question

I created 9 QPushButtons which objectName's are E1, E2, E3, ..., E9. Now, I want to update their text field with strings I get from a database, so I want to do something like this:

query="SELECT evento FROM eventos;"
cur.execute(query)

i=1
for fetch in cur:
    evento=str(fetch)
    objectname="E"+str(i)
    self.objectname.setText(evento)
    i+=1

This loops fetches 9 lines (9 strings) and updates the buttons' display text. The problem is that I have to tell it which button to update and I can't figure out how to do it dynamically since the lines: objectname="E"+str(i) and self.objectname.setText(evento) won't work because AtributeError: 'MyWindowClass' object has no attribute 'objectname'

Is this a duplicate of: [How to find an object by name in pyqt?](http://stackoverflow.com/questions/19048657/how-to-find-an-object-by-name-in-pyqt) You want to lookup objects depending on the *Qt name* you have set in their `objectName` property? — Bakuriu, Mar 17 '16 at 20:09
Yes germn! It works perfectly! Thank you so much! I could kiss you right now! Didn't know about this gettattr() function. — Diogo Magalhães, Mar 17 '16 at 20:10

Use getattr():

getattr(self, "E"+str(i)).setText(evento)

You can also use

self.findChild(QtGui.QPushButton, 'E{0}'.format(i)).setText(evento)
