Вопросы про переменную PYTHONPATH 🔸 Как она определяет пути поиска модулей при импорте? Пути поиска модулей находятся в списке sys.path. Как формируется этот список? Исходя из документации мы может выделить 3 основных этапа. ▫️Путь к запускаемому скрипту или рабочая директория ▫️ Переменная PYTHONPATH ▫️ Стандартные пути к библиотекам Это значит, что все три этапа выполняются в момент инициализации интерпретатора. Результат заполняет список sys.path. В том числе и пути, указанные в переменной PYTHONPATH. 🔸 Можно ли добавлять новые пути в эту переменную в Python-коде? Можно, но учитывая, что используется она только во время старта интерпретатора, никакого эффекта это иметь не будет. Для изменения путей поиска модулей в коде нужно изменять непосредственно список sys.path. 🔸 Можно ли указать много путей для поиска? Да, с помощью переменной PYTHONPATH можно указать несколько директорий, разделённых символом разделения пути. Для Linux это символ ":", для Windows это ";". Например: export PYTHONPATH=/mnt/libs:~/mylibs #basic#tricks

🌎 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 ​
