Многие из тех кто активно работал с Python2 несколько удивлены, почему в Python3 удобная функция reload() переехала из builtin в imp а потом и в importlib?
Ну было же удобно! А теперь лишний импорт😖
Дело в том, что начиная с Python3.3 функция reload() переписана на Python вместо Cи.
Что это нам даёт?
🔸 Такой код проще поддерживать и развивать
🔸 Python код легче читать, изучать и понимать.
Сравните это ➡️ и это ➡️.
🔸 Как результат пункта 2, проще писать свои расширения импорта. Например, пользовательский импортёр с какой-либо хитрой логикой по аналогии с импортом из zip архивов.
А есть ли у этого решения недостатки? Да, они всегда есть.
🔹 Так как это не builtin функция, её следует импортнуть перед использованием
🔹 Скорость замедлилась примерно на 5%. Очевидно, что это совершенно не критично. К тому же от версии к версии логика импорта будет оптимизироваться и ускоряться.
В самом начале файла importlib/__init__.py мы видим такой импорт:
import _imp # Just the builtin component, NOT the full Python module
То есть часть функционала по прежнему написана на Си, но достаточно низкоуровневая.

News: #Australia issues ‘do not travel’ advisory for #Tigray, #Amhara, and other regions in #Ethiopia
The Australian government has issued a “do not travel” advisory for Ethiopia’s Tigray regional state, warning that the security situation could deteriorate rapidly with little or no warning, according to its latest update on the Smartraveller travel advisory platform.
In the update, Australian authorities urged their citizens currently in Tigray to leave when it is safe to do so using commercial means, noting that Australia’s ability to provide consular assistance in the region remains “extremely limited.” Travelers were also advised to follow local authorities’ instructions and to shelter indoors in the event of civil unrest or armed conflict.
Beyond Tigray, Australia continues to advise against all travel to the Amhara, #Benishangul-Gumuz, and #Gambela regional states, as well as border areas with #Eritrea, #Sudan, #South_Sudan, #Kenya, and #Somalia,....
