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.

#RedBook🌷 Tulipa affinis (Relative Tulip)
A rare endemic plant of the Western Pamir-Alay region, found only in limited areas. Its bright red flower with a black center and yellow border makes the plant especially striking — but this beauty is also one of the reasons it is often destroyed.
📍Distribution
In Uzbekistan, it grows in the Jizzakh, Samarkand, and Navoi regions — on the Turkestan and Malguzar mountain ranges and in the Nurata Mountains. It is also found in Kyrgyzstan and Tajikistan. The plant grows on rocky slopes, in gorges, and among shrubs and juniper woodlands.
🌱Plant characteristics
▫️ Perennial bulbous plant, 15–25 cm tall
▫️ Blooms in April–May
▫️ Reproduces by seeds and vegetatively
▫️ Occurs rarely in nature — as single plants or small groups
⚠️Why the species is under threat
The main reasons for the population decline are mass collection of flowers and livestock grazing, which destroy the plant’s natural habitat.
🌿Conservation status
The plant has been cultivated in the Botanical Garden of the Academy of Sciences of the Republic of Uzbekistan since 1957 and is protected in Zaamin State Reserve and Nurata State Reserve.
💚 Protecting rare plants is an important part of preserving biodiversity. Take care of nature and do not pick wild flowers. ☘️Read the latest environmental news on the @ekologuz page. Follow us and send your suggestions and wishes via @eklguz_bot

Also found in:
– Tajikistan
– Kyrgyzstan
– Kazakhstan
🌱 Habitat

🔢 Population
Occurs as solitary plants or in small clusters.
♻️ Reproduction
Reproduces by seeds and vegetatively.
⚠️ Threats and Causes of Decline
– Trampling and damage caused by grazing livestock
– Use of the plant as firewood
These factors lead to a steady reduction in population and habitat range.
🌿 Domestication and Importance
Cultivated in all botanical gardens of Central Asia, in specialized horticultural research plots, and at breeding stations for developing new varieties.
🛡 Conservation Measures
– Protected in the Nurata and Chatkal State Nature Reserves
– Under protection in the Ugam–Chatkal National Park ☘️Read the latest environmental news on the @ekologuz page. Follow us and send your suggestions and wishes via @eklguz_bot

🦅 Peregrine Falcon — the fastest bird in the world
The peregrine falcon can reach speeds of up to 390 km/h during a dive. These majestic predators hunt birds and small mammals, playing a vital role in maintaining the balance of ecosystems.
❗️ Important: the peregrine falcon is listed in the Red Book of Uzbekistan. Its population is under threat due to habitat destruction, poaching, and environmental pollution.
🌿 Protecting peregrine falcons is a contribution to preserving the biodiversity and future of our country’s nature.
