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

🌎 Giant clouds called molecular clouds are where new stars are born. These clouds, made mostly of hydrogen gas, can stretch for hundreds of light-years. The Orion Molecular Cloud Complex, one of the closest such regions, is located about 1,350 light-years from Earth and is home to thousands of young stars. ✨ #astronomy⚡#stars⚡#nebula 👉subscribe Interesting Planet 👉more Channels ​

🪐 In the galaxy NGC 1999, astronomers observed a mysterious, dark patch once believed to be a dense cloud of cosmic dust blocking light. However, further study revealed this region is actually a rare "hole" in the nebula—an empty cavity punched through the glowing gas by powerful stellar winds from young, massive stars, making it a striking example of cosmic sculpting at work. ✨ #nebula⚡#phenomena⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries ​

🪐 In the Carina Nebula, the massive star Eta Carinae is surrounded by strange, expanding clouds known as the Homunculus Nebula—vast lobes of gas and dust hurled into space by a series of explosive outbursts in the 19th century. These violent eruptions have sculpted one of the most complex and enigmatic structures ever observed, with glowing filaments and mysterious hidden cavities still being revealed by the Hubble Space Telescope. ✨ #EtaCarinae⚡#nebula⚡#mysteries 👉subscribe Universe Mysteries

🪐 The Egg Nebula (CRL 2688) in Cygnus glows with haunting, layered arcs of dust and gas, shaped by fierce stellar winds from a dying central star. These concentric shells, illuminated by starlight scattered through dense clouds, reveal a dramatic portrait of a Sun-like star in its brief, enigmatic transition into a planetary nebula. ✨ #nebula⚡#stars⚡#transformation⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In the star-forming region of the Orion Nebula, astronomers have identified "proplyds"—dense disks of gas and dust swirling around newborn stars. These proplyds are being sculpted by fierce ultraviolet radiation from nearby massive stars, their bright comet-like tails pointing away from blazing giants such as Theta1 Orionis C. ✨ #Orion⚡#proplyds⚡#nebula 👉subscribe Universe Mysteries

🪐 The Boomerang Nebula in the constellation Centaurus is the coldest known place in the universe, with temperatures dropping to a chilling -272°C—colder than the cosmic microwave background itself. This young planetary nebula expels gas at incredible speeds, creating a ghostly, double-lobed shape that shrouds its dying central star in frigid mystery. ✨ #BoomerangNebula⚡#coldest⚡#nebula 👉subscribe Universe Mysteries

🪐 The star AG Carinae, located about 20,000 light-years away, is a rare example of a "luminous blue variable"—an unstable giant star that can erupt in massive outbursts, shedding huge shells of gas and dust. AG Carinae shines millions of times brighter than the Sun and is surrounded by a glowing nebula created by its violent eruptions, making it one of the most volatile and spectacular stars in our galaxy. ✨ #unusualstars⚡#stellareruption⚡#nebula⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels ​

🪐 In the center of the galaxy NGC 2392, also known as the "Eskimo Nebula," astronomers have detected fast, energetic jets of gas blasting outwards at speeds of over 200 kilometers per second. These jets, launched by the dying central star, punch through surrounding shells of glowing gas, creating intricate, layered patterns that make this nebula one of the most visually stunning and mysterious cosmic objects observed by the Hubble Space Telescope. ✨ #nebula⚡#jets⚡#emission⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries ​
