check for non valid object

[user4592357]

say i have such code:

...
self.mw = QMainWindow()
self.create_dock_widgets()

...
def create_dock_widgets(self):
    # should i check if window is valid object?
    self.mw.addDockWidget...

should i actually do it?

And do what if it isn't? You're only going to raise, and self.mw.addDockWidget will raise anyway if it isn't. Plus self.mw = QMainWindow() would have raised in the first place if it couldn't create a main window.

Of course you can check everywhere if you wish. But that can be a lot of code. I wouldn't bother here.

P.S.
Unless you're doing it for a school project. In which case, goodness knows...
