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
alias py="python3 /home/username/my_console.py"

🔋The Smartphones With the Longest-Lasting Batteries
Every #smartphone users know the dilemma: It doesn’t matter how great your latest-generation smartphone is or which cutting-edge features it contains - the device still runs on old-fashioned electricity it draws from its battery, often the weakest part of the phone. With the number of apps people use and time they spend on their smartphone increasing, battery woes are all too common - the prevalence of powerbanks and charging stations popping up in different places certainly tell that story.

📱Smartphone Dominance
Following up on the poll above, although not producing the same results, here are some interesting stats from Pew Research Centre: #Smartphone users are now more likely to go online using their mobile phone than with some other type of device.
For smartphone owners, their mobile devices now outpace more traditional means of accessing the web. 46% of them say when using the internet, they mostly do so on their phone. This represents a 12% increase from 2013 when 34% of these users said this.
At the same time, the share of smartphone users who say a desktop, laptop or tablet computer is their primary device for going online has fallen from 53% in 2013 to 30% today. Roughly a quarter of smartphone users say they equally use a cellphone or a desktop, laptop or tablet computer when going online, up from 12% six years prior.
