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. #basic

🌎 Glowing deep-sea animals like the comb jellyfish and dragonfish create their own light using bioluminescence. This adaptation helps them hunt, attract mates, or avoid predators in pitch-black ocean depths. Some dragonfish possess "invisible" red bioluminescence, seen only by their own kind, for stealthy communication. ✨ #ocean⚡#animals⚡#bioluminescence 👉subscribe Interesting Planet 👉more Channels ​

🌎 Shrouded in darkness, the “midnight zone” of the ocean lies below 1,000 meters, where sunlight can’t reach and pressure crushes like a dozen elephants. Creatures here glow with bioluminescence and withstand freezing cold, revealing how life adapts to our planet’s most mysterious depths. ✨ #ocean⚡#bioluminescence⚡#deepsea 👉subscribe Interesting Planet ​

🌎 Lightning bugs, or fireflies, create their glow through a special enzyme called luciferase. This reaction produces cold light, wasting almost no energy as heat—a marvel of natural engineering for nighttime signaling. ✨ #bioluminescence⚡#insects⚡#nature 👉subscribe Interesting Planet

🌎 Glowing tides known as bioluminescent bays light up in places like Puerto Rico. Microorganisms called dinoflagellates produce blue-green light when stirred by waves or movement. The brightest, Mosquito Bay, can host up to 700,000 glowing organisms in just one liter of water. ✨ #bioluminescence⚡#ocean⚡#phenomenon 👉subscribe Interesting Planet 👉more Channels ​

🌎 Glowing waves known as “sea sparkle” can light up coastlines at night. This effect is caused by bioluminescent plankton emitting blue light when disturbed. Some blooms stretch for kilometers and are most often seen in warm coastal waters. ✨ #bioluminescence⚡#ocean⚡#plankton 👉subscribe Interesting Planet 👉more Channels ​

🌎 Somewhere in the world’s oceans, the “milky sea” phenomenon can make water glow bright blue for up to several days. Caused by massive colonies of bioluminescent bacteria, these rare glowing patches can cover areas larger than 15,000 square kilometers—visible even from space. ✨ #ocean⚡#mysteries⚡#bioluminescence⚡#bacteria 👉subscribe Interesting Planet ​
