How to draw a simple horizontal rule in a QWidget?

Question

I just want to add a horizontal rule (just like <hr> in HTML, see below) to a QWidget.

But I failed to find such a class in the documentation.
Could anyone give me example code?

This can be done using a QFrame and setting the shape with setFrameShape(QFrame::HLine) and frame shadow using setFrameShadow(QFrame::Sunken). I just noticed that you are working in Python. My answer uses C++ syntax. Hopefully it is sufficient :)
