Как работает функция reload()? Эта функция нужна для того, чтобы перезагрузить изменившийся код из py-файла без рестарта интерпретатора. Дело в том, что любой импортированный модуль при повторном импорте не будет перечитывать файл. Функция импорта вернёт уже загруженный в память объект модуля. Чтобы обновить код, нужно либо перезапустить всю программу, либо использовать функцию reload() from importlib import reload reload(my_module) 🔸 Функция reload() принимает в качестве аргумента только объект модуля или пакета. Она не может перезагрузить класс или функцию. Только весь файл целиком! 🔸 Перезагрузка пакета перезагрузит только его файл __init__.py, если он есть. Но не вложенные модули. 🔸Она не может перезагрузить ранее не импортированный модуль. 🔸При вызове функция reload() перечитывает и перекомпилирует код в файле, создавая новые объекты. После создания новых объектов перезаписывается ранее созданный неймспейс этого модуля. Это значит, что если где-то этот модуль импортирован через import и обращение к атрибутам происходит через неймспейс (имя) модуля, то такие атрибуты обновятся. Если какие-либо объекты из этого модуля импортированы через from то они будут ссылаться на старые объекты. Напишем простой модуль # mymodule.py x = 1 Теперь импортируем модуль и отдельно переменную х из модуля >>> import mymodule >>> from mymodule import x >>> print(mymodule.x) 1 >>> print(x) 1 Не перезапуская интерпретатор вносим изменения в модуль # mymodule.py x = 2 Делаем перезагрузку модуля и проверяем х ещё раз >>> reload(mymodule) >>> print(mymodule.x) 2 >>> print(x) 1 То же самое будет если присвоить любой объект переменной (даже словарь или список) Повторный импорт обновляет значение >>> from mymodule import x >>> print(x) 2 🔸Созданные инстансы классов не обновятся после перезагрузки модуля. Их придётся пересоздать. #tricks#basic

Local Conference of Youth on Climate Change was launched in Astana as part of the annual UN Climate Change Conference of Youth. The event was organized by the National Conservation Initiative, Sustainable Development Solutions Network and Nazarbayev University. "The world needs a collective effort to limit global warming to 1.5 degrees. We are not on track. #Kazakhstan and #CentralAsia are one of the regions to bear the most acute effects of climate change. The imminence of the #environmental degradation requires immediate action and unwavering commitment to the #climategoals the region has set. As Kazakhstan is taking steps towards #carbonneutrality by 2060, we support the government, industry and civil society to underpin this with concrete actions," - said Johannes Baur, Head of Сooperation at the EU Delegation to Kazakhstan.
