I've recently installed Pylance as python language server on VSCode. I'm building an app with PyQt5. In the script under question, I'm inheriting a UI python script automatically generated by pyqt5 uic. listProfiles is a QListView object generated in Ui_ProfileMainWindow

class ProfileMainWindow(QMainWindow, Ui_ProfileMainWindow):
    def __init__(self, model = None):
        super().__init__()
        self.setupUi(self)
        if model:
            self.listProfiles.setModel(model)

Pylance is capable of seeing the listProfiles attribute and recognizes it as a QListView object:

But no autocomplete is provided for it:

Furthermore, a when the mouse is over self.listProfiles, a generic Any type is pointed out for it:

I really can't figure out what's going on. I'd like to assume I've messed something up before thinking of a bug.

Since it's been a day I'm working with Pylance, I'd say that this was not happened as soon as I installed the language server, but I'm not sure about this piece of information, since I was working on another part of the script and, maybe, I just didn't realize that

No errors are in the code, since the app run and works properly.

EDIT 1

The problem is solved swapping the order of the inherited class:

class ProfileMainWindow(Ui_ProfileMainWindow,QMainWindow):
    def __init__(self, model = None):
        super().__init__()
        self.setupUi(self)
        if model:
            self.listProfiles.setModel(model)

Still can't figure out why and what's going on.
