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 exoplanet Kepler-438b, orbiting a red dwarf star about 470 light-years from Earth, is one of the most Earth-like worlds found in terms of size and temperature. Scientists have carefully measured its position in the “habitable zone”—the region around a star where liquid water might exist, a key ingredient scientists believe is necessary for life as we know it. ✨

🪐 Astronomers have pinpointed the exoplanet LP 890-9 c, located about 105 light-years away in the constellation Eridanus, as one of the most promising places for life outside our solar system. This rocky world orbits within its star’s habitable zone—the region where temperatures could allow liquid water to persist, making it a key target in the search for planets that might support life as we know it. ✨

🪐 Astronomers have discovered that the exoplanet Gliese 486 b, about 26 light-years away in the constellation Virgo, is a rocky world with surface temperatures hot enough to melt lead. Even though it's likely too warm for life as we know it, its firm, Earth-like surface and relatively close distance make it an important candidate for studying rocky planets outside our solar system—and for searching how and where life might survive under extreme conditions. ✨

🪐 Around the distant red dwarf star LHS 1140, about 49 light-years from Earth, astronomers have discovered a rocky exoplanet called LHS 1140 b that sits right in the star’s “habitable zone”—the area where temperatures could allow liquid water to exist. Recent observations suggest its atmosphere may still be intact, making LHS 1140 b one of the most promising known worlds for the search for life beyond our solar system. ✨

🪐 Beyond our solar system, two intriguing exoplanets orbit the star Kepler-62: Kepler-62e and Kepler-62f. Both are considered "super-Earths" (planets larger than Earth but smaller than Neptune) and sit inside their star’s habitable zone, a region where temperatures might allow water to exist as a liquid—a key ingredient for life as we know it. ✨

🪐 Orbiting the cool red dwarf star Ross 128, about 11 light-years away, the exoplanet Ross 128 b is roughly Earth-sized and lies in its star’s temperate zone, where conditions might allow liquid water. Although Ross 128 is much dimmer than the Sun, its calm nature means less intense flares, making Ross 128 b an especially intriguing place in our search for potentially habitable worlds beyond our solar system. ✨

🪐 Astronomers have identified Kepler-442b, an exoplanet about 1,200 light-years away in the constellation Lyra, as a strong candidate for hosting life. This rocky world orbits in its star’s habitable zone—a region where temperatures could allow liquid water—and is just slightly larger than Earth, making it an intriguing example of a real planet with conditions that might one day support living organisms. ✨

🪐 Scientists have identified the exoplanet Gliese 581d, orbiting a red dwarf star about 20 light-years away, as one of the earliest potentially habitable worlds outside our solar system. Gliese 581d lies within its star's habitable zone, where temperatures might allow liquid water to exist, making it a key target in the search for life beyond Earth. ✨

🪐 Just 39 light-years away, the exoplanet TRAPPIST-1e circles its cool red dwarf star in the habitable zone, where temperatures might allow liquid water. Scientists have found that TRAPPIST-1e has a rocky surface and, unlike some of its neighbors, could have the right conditions for life as we know it. ✨

🪐 Saturn’s moon Titan is one of the most intriguing places in the solar system where life could exist because it has lakes and rivers of liquid methane and ethane—chemicals similar to gasoline on Earth. While it’s far too cold for liquid water, scientists are captivated by the idea that life, if it ever formed there, would be fundamentally different from anything on our planet. ✨

🪐 Astronomers have found signs that Uranus’s moon Miranda may hide a subsurface ocean of liquid water beneath its fractured, icy crust. The unique patterns of ridges and canyons on Miranda, revealed by Voyager 2, suggest internal heat could provide the conditions needed for liquid water—a key ingredient for life—even on this tiny, distant world. ✨
