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

It’s May the 4th! Saving the earth is in your hands, so may the force be with you. Like ice cream in this hot Singapore weather, the earth’s great ice caps are melting due to global warming! It’s time to ask ourselves if we have done enough for the earth. If not, start here: www.mewr.gov.sg/climateaction#ClimateActionSG
