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.

Sudden rain showers are common in Singapore, so if you leave your pails or plant pots where they can collect water, do pay extra attention and drain these containers if they have collected any water.
Here’s a checklist for a thorough #MozzieWipeout: https://go.gov.sg/dengue-checklist
Have you emptied out your flower pot plates after watering your plants today? These plates tend to collect water, and can become mosquito breeding habitats if left unattended. Be sure to add emptying out the flower pot plates to your “To-do List” after watering your plants! Here’s a checklist for a thorough #MozzieWipeout: https://go.gov.sg/dengue-checklist
The annual National Dengue Prevention Campaign was launched today, to rally everyone to take urgent action to prevent mosquito breeding and a possible surge in dengue cases, amidst the continued high Aedes aegypti mosquito population, and higher circulation of less common Dengue virus serotypes.
The fight against dengue involves all of us. Let’s step up dengue prevention by doing the #MozzieWipeout regularly. go.gov.sg/mozzieproof

Staying home during this COVID-19 period has brought out the green thumb in many of us. And yet, with interest comes responsibility, too! Set a daily reminder to keep your plants nourished and your home protected from dengue too: https://go.gov.sg/dengue-checklist#MozzieWipeout
The gully traps in our homes are perfect for mosquito multiplication! Cover rarely used gully traps or install anti-mosquito valves, to prevent mosquito breeding. Here’s a ‘Check and Protect’ checklist for your thorough #MozzieWipeout today: https://go.gov.sg/dengue-checklist
Do you know where are the favourite places for mosquitoes to lay their eggs?
Pails, flower pot plates/trays and ornamental vases are some of the persistent mosquito breeding habitats in homes. It’s time to search for and destroy these breeding habitats! If you’re not sure how, get started here: https://go.gov.sg/dengue-checklist#MozzieWipeout
The number of weekly dengue cases has declined by more than 50% from its peak this year. However, a 12% increase in the Aedes aegypti mosquito population was detected in the last 3 weeks.
So let’s not let our guard down; continue doing the #MozzieWipeout at least once a week and taking protective actions (go.gov.sg/stopdenguenow). You can also get regular alerts on areas with higher Aedes mosquito population and dengue clusters on myENV app (www.nea.gov.sg/myENV) with this step-by-step guide!
Think it’s impossible for mosquito eggs to hatch in your dish tray, mere inches away from your cups and plates? It certainly isn’t. All mosquitoes need is a 20 cent-sized drop of water to breed. Time to do a thorough check in your house! #MozzieWipeouthttps://go.gov.sg/dengue-checklist
Besides doing the #MozzieWipeout, take these 3 simple actions to protect yourself and your loved ones, especially if you live in a dengue cluster area: Spray, Apply, Wear. More tips here: www.nea.gov.sg/stop-dengue
