В прошлом посте говоря "Все вызовы теперь одинаковы" я несколько слукавил. Всё-таки есть в этом зоопарке версий некоторая несовместимость вызов которой просто так не унифицировать. Эти моменты вынесены в отдельный модуль QtCompat (compatibility). Там не так много функций но они довольно полезны.
Этот модуль содержит унификаци модуля shiboken2, функций loadUi, translate и несколько переименованных функций классов или изменённую сигнатуру аргументов и возвращаемых значений. Это единственное исключение из правила когда вам потребуется где-то изменить свой код кроме импортов и этот код не похож на обычный код PySide2.
Например, в PyQt4 и PySide есть метод
QHeaderView.setResizeMode
Для PyQt5 и PySide2 они были благополучно переименованы в
QHeaderView.setSectionResizeMode
Чтобы применить этот метод следует использовать такой код
from Qt import QtCompath
header = self.horizontalHeader()
QtCompat.QHeaderView.setSectionResizeMode(header, QtWidgets.QHeaderView.Fixed)
Унификация загрузки UI файлов:
# PySide2
from PySide2.QtUiTools import QUiLoader
loader = QUiLoader()
widget = loader.load(ui_file)
# PyQt5
from PyQt5 import uic
widget = uic.loadUi(ui_file)
# Qt.py
from Qt import QtCompat
widget = QtCompat.loadUi(ui_file)
Хорошо что таких моментов не много и их легко запомнить.
Полный список можно посмотреть в таблице.

Good deals may be tempting but just because it’s on discount doesn’t mean you have to buy it.
Reduce food wastage during the upcoming year-end festivities:
✅ Plan your meals and prep a shopping list
✅ Order only what you can finish
