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.

The custom of putting candles on cakes dates back to the ancient Greeks, who honored the goddess Artemis by placing lit candles on round, moon-shaped cakes. They believed that the smoke from the candles carried their wishes and prayers up to the gods in the sky.

The name Ethiopia comes from the ancient Greek word “Aithiopia.” It comes from “aithō” (to burn) and “ops” (face), meaning “burnt face.” Ancient Greeks used this word to describe dark-skinned people living south of Egypt. The word appears in the works of Homer, who lived around the 8th century BCE. 🌍🔥

🌍 Over 2,200 years ago, the Greek mathematician Eratosthenes calculated Earth’s circumference using only a stick and his brain — and he was almost exactly right! 📏
By observing shadows in two cities, he calculated the Earth was about 40,000 km around. Ancient genius at its finest!

In ancient Athens, some elite men formed socially recognized relationships with adolescent boys called eromenos. The adult, erastes, acted as a mentor, teaching the boy skills and introducing him to society. These relationships were accepted at the time and had strict social rules: the boy had to be young and not fully grown. Once he reached adulthood, remaining in that role was considered inappropriate..
