Для тех кто пишет расширения на PyQt/PySide для CG-софтов.
Когда я только начинал писать тулзы под Maya (тогда еще версия 2010-2011) мне приходилось ручками ставить PyQt4 под Maya. Даже написал мануалы по установке на своём сайте. Но потом стал доступен из коробки PySide и позже он обновится до PySide2. Для некоторых систем была поддержка PyQt5.
И как простому разработчику поддерживать этот зоопарк? Ведь хочется чтобы тул работал на любой версии (вы тоже делали модуль что-то типа import_qt.py?😁)
На помощь приходит проект Qt.py который поставил себе цель унифицировать использование Qt-биндингов вне зависимости от среды где запускается код. Те, кто давно пишут на Qt, скорее всего знают этот проект.
Он стал стандартом для CG-индустрии и используется в топовых студиях и проектах.
Qt․py помогает запускать один и тот же код на разных платформах с разными вариантами Qt-библиотек. Это может быть как интеграция в CG-софт, так и переносимость стендалонов между разными платформами с разными версиями Python.
Я решил рассказать о некоторых особенностях работы с этой библиотекой.
Сегодня о том, как установить и использовать Qt․py и что это вам даёт.
Установка
pip install Qt.py
Чтобы начать использовать Qt․py в коде достаточно заменить импорт вашего варианта Qt-биндинга на Qt․py
from [PySide|PyQt4|PySide2|PyQt5] import QtWidgets
=>
from Qt import QtWidgets
Теперь ваш код будет поддерживать любой вариант биндинга Qt в Python.
При этом не потребуется использовать if-else конструкции под разные версии. Все вызовы теперь одинаковы.
Всё что нужно сделать, это написать его по правилам PySide2. Именно эта версия была взята за основу.
Приоритет импорта такой:
1. PySide2
2. PyQt5
3. PySide
4. PyQt4
Что именно загрузилось можно посмотреть в переменной __binding__
>>> import Qt
>>> Qt.__binding__
'PySide2'
Приоритет имопрта можно изменить через переменные QT_PREFERRED_BINDING и QT_PREFERRED_BINDING_JSON. Причем под каждый проект оверрайды можно настраивать индивидеально.

📍 Mount Teide, Tenerife Island, Spain 🇪🇸
🌋 Mount Teide is located in the center of the largest of the Canary Islands - Tenerife. The mountain, which can be seen today from any point on the island of Tenerife, grew more than a hundred thousand years ago from the depths of the ancient stratovolcano Las Cañadas, the top of which once collapsed inward under the weight of the erupting lava.
This majestic peak, standing at 3,718 meters (12,198 feet), is the highest point in Spain and the third highest volcano in the world, rising from its base on the ocean floor. The surrounding Teide National Park boasts an otherworldly landscape of volcanic craters, lava fields, and unique flora and fauna. A cable car ride to the top offers breathtaking views of the island and the Atlantic Ocean beyond. 🌋🚠

🇪🇸🇮🇨Spain says over 1,000 migrants reached its Canary Islands in 3 days as more attempt deadly crossing
More than 1,000 migrants from sub-Saharan countries arrived in Spain's Canary Islands in 18 boats over the past three days, Spain's marine rescue service said on Monday.
The archipelago off northwest Africa has seen a surge in migrant arrivals in recent weeks as more people from West Africa attempt to get their, which is a dangerous trip.
Officials say 7,270 migrants arrived in January, about as many as in the first six months of 2023.
Most of the boats depart from Mauritania. Spanish Prime Minister Pedro Sánchez and European Commission President Ursula von der Leyen will visit the West African country on Thursday to encourage authorities to try to curtail the departures.

🐟 Rare Encounter with the “Sea Devil” near the Canary Islands!
For the first time in history, biologists managed to capture this mysterious deep-sea predator on video. Usually, only larvae or dead specimens are observed, as anglerfish live at extreme depths where almost no light reaches. But this time, the fish rose to the surface and appeared in front of the researchers’ camera — a truly unique observation for science!
