Qt/PyQt 5.9.x. Correct way to get an "enumeration flags" to return 0?

I am having trouble getting a method returning "flags" to return 0/zero/no
flags.

Specifically, I am translating a Qt example (
https://doc.qt.io/qt-5/qtwidgets-layouts-flowlayout-example.html,
https://code.qt.io/cgit/qt/qtbase.git/tree/examples/widgets/layouts/flowlayout),
from C++ to PyQt.  It overrides QLayout::expandingDirections() as follows:

Qt <https://doc.qt.io/qt-5/qt.html>::Orientations
FlowLayout::expandingDirections() const{
    return 0;}

Qt::Orientations is a "flags", with the two defined enumeration values
being 1 & 2.

Basically if I define my Python override to return 0 I get runtime error:

invalid result from JFlowLayout.expandingDirections(), int cannot be
converted to PyQt5.QtCore.Orientations in this context

<class 'TypeError'>

If I return QOrientations() that works, but I'm unsure if that guarantees
to return zero.

If I return QOrientations(0) that too works, but my PyCharm IDE marks the
source with an "Unexpected type 'int'" for the parameter.

Which is the "correct"/"best" way to return a "flags" like this from
Python/PyQt, please?
