Ранее мы уже говорили о том, как выполнить какой-либо код перед открытием интерактивной консоли.
Расскажу еще один способ! На самом деле, даже запустив интерпретатор в обычном режиме с выполнением скрипта из файла вы можете в любом месте активировать интерактивный режим. Или даже несколько по очереди. За это отвечает модуль code.
Как это может пригодиться?
🔸 Вам не хватает pdb и хочется больше "власти"
🔸 Нужно запросить у юзера данные в достаточно сложном виде. В этом случае можно попросить его создать что ему надо и сохранить в определённую переменную, с которой потом и работать.
🔸 Нужна изолированная среда для выполнения каких-либо действий.
🔸 Просто забавы ради😁
Запускается консоль очень просто
import code
ic = code.InteractiveConsole()
try:
ic.interact()
except SystemExit:
pass
Выход обратно на предыдущий уровень происходит как обычно, вызов функции exit() или клавиши Ctrl+D(Ctrl+Z для Windows).
Я набросал простой пример с некоторым функционалом
🔹 Меняются символы приглашения
🔹 В неймспейсы добавляются дополнительные объекты
🔹 Считается время, проведённое в интерактивном режиме
🔹 Скрипт просит юзера заполнить переменную и по выходу распечатывает её значение
Код здесь ↗️
Для запуска сохраните код в файл и запускайте как обычный скрипт.
python my_console.py
Для быстрого запуска можно сделать отдельный алиас

🪐 The galaxy HD1, discovered in 2022, may be the most distant known object in the universe—its light has traveled more than 13.5 billion years to reach us. Observing HD1 gives astronomers a rare window into the universe just 300 million years after the Big Bang, offering clues to how the earliest galaxies and stars began to form in the cosmic dawn. ✨

🪐 The James Webb Space Telescope has spotted the earliest known supermassive black holes in galaxies that formed less than a billion years after the Big Bang, such as in the galaxy GN-z11. These giant black holes are much more massive than scientists expected for such young galaxies, forcing astronomers to rethink how quickly these cosmic monsters can grow in the very early universe. ✨

🪐 The James Webb Space Telescope has uncovered giant, star-forming galaxies such as CEERS-93316 that existed less than 250 million years after the Big Bang. These ancient galaxies are much larger and brighter than scientists expected, revealing that massive cosmic structures began assembling much earlier in the universe’s history than previously thought. ✨

🪐 The cosmic microwave background—often called the afterglow of the Big Bang—shows that the universe was filled with a hot, dense plasma about 380,000 years after its birth. When the universe cooled enough for atoms to form, light was finally able to travel freely, leaving behind a faint, uniform glow that we still detect today and which blankets galaxies like the Milky Way and Andromeda in every direction. ✨

🪐 The star SDSS J102915+172927 in the constellation Leo is one of the most chemically primitive stars ever found, containing almost no elements heavier than hydrogen and helium. Its incredibly simple makeup suggests it formed from material left over from the very first stars in the universe, making it a true relic from the cosmic dawn. ✨

🪐 The cosmic microwave background holds a hidden fingerprint—tiny temperature fluctuations mapped in exquisite detail by satellites like Planck reveal how the first stars and galaxies, such as those in the ancient cluster Abell 2744, grew from initial small ripples in the early universe. These faint variations, just millionths of a degree, became the seeds around which all the cosmic structures we see today first assembled. ✨

🪐 The cosmic microwave background, a faint glow that bathes the entire universe, carries subtle imprints called "acoustic peaks"—tiny wiggles in its temperature pattern, mapped by observatories like Planck. These acoustic peaks reveal the sound waves that rippled through the hot, dense plasma of the early universe, showing how matter and energy once "rang" together before the first atoms even formed. ✨

🪐 Stretching across all of space, the cosmic microwave background is sprinkled with mysterious "hot" and "cold" rings—subtle patterns first mapped by the Planck satellite. One of these ring structures, dubbed the "CMB rings," shows up as smooth, circular features and could be the leftover imprint of massive waves moving through the young universe, giving scientists a unique window into the conditions just hundreds of thousands of years after the Big Bang. ✨
