[Question] Changing the preferred binding order from Python code

I am aware of the QT_PREFERRED_BINDING environment variable, but I would like to know if it is possible to alter the order of bindings directly from python. I am currently using Qt.py through vendoring, so I know that I could also alter this manually by changing default_order = ("PySide2", "PyQt5", "PySide", "PyQt4"). Thanks.

Ah, yes you are right, this would override any existing variable.

How about asking for it first, and overriding if it doesn’t already exist?

import os

if "QT_PREFERRED_BINDING" not in os.environ:
  os.environ["QT_PREFERRED_BINDING"] = os.pathsep.join(
    ["PySide2", "PyQt5", "PySide", "PyQt4"]
  )

import Qt

You are most welcome.
