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.

UN EXPERTS DEMAND SAFE PASSAGE FOR ‘MADLEEN’
JOIN THEM
Today, UN experts called for safe passage for the Madleen — our civilian ship carrying vital aid and international volunteers to Gaza.
Now we need your voice. Let’s turn international law into action.
📣 Take one minute: go to bit.ly/IsraelOnNotice and send a letter to the Israeli government, UN officials, and diplomatic missions demanding that Israel abide by international law and refrain from attacking, sabotaging or otherwise interfering with the Madleen and her mission.
Together, we can open a people’s sea corridor to Gaza. #SafePassage#BreakTheSiege#FreedomFlotilla
Six of the seven U.S. citizens aboard the Freedom Flotilla’s ‘Handala’ just read a powerful open letter to Donald Trump and the U.S. government. From the founder of Amazon Labor Union’s to a U.S. war veteran, a lawyer, a marine rescue worker, a human rights attorney, and an actor—each one delivered a searing truth: the U.S. is an active participant in Israel’s war crimes against Palestinian children in Gaza. If the U.S. does not support the deliberate starvation of children, they should guarantee safe passage of ‘Handala’.
‘Handala’ plans to deliver food, medicine, and baby formula to Gaza in a few days. They are unarmed, trained in nonviolence, and yet, are under threat by Israel. If anything happens to them, the world will know who is responsible.
Share this. Tag your politicians. Break the silence. Let the world see who’s standing on the right side of history.

🚨 ACTION ALERT: The UK MUST protect ‘Madleen’ 🚨
The ‘Madleen’ is a UK-flagged civilian ship sailing to Gaza with life-saving aid as part of the #FreedomFlotilla. The UK has a legal duty to protect its vessel and the civilians aboard from Israeli interference.
🇬🇧 Under international law, the UK must:
• Prevent genocide
• Reject Israel’s illegal blockade of Gaza
• Defend its flagged ship from unlawful attacks
Support us by taking action! Contact the Foreign Office and your MP. Demand protection for the ‘Madleen’ and accountability for any aggression.
