Наверняка вы замечали, что в Python есть удобная функция для получения переменной окружения os.getenv(NAME) И её "сестра" для создания или изменения переменных окружения os.putenv(NAME, VALUE) Но почему-то putenv() не работает как должно. Энвайромент не обновляется! os.putenv('MYVAR', '1') print(os.getenv('MYVAR')) ... и ничего 😴 Почему так? На самом деле энвайромент обновляется, но это значение не добавляется в словарь os.environ. Откройте исходник функции os.getenv(). Это просто шорткат для os.environ.get() В то время как putenv() это built-in С-функция. Словарь os.environ (или точней класс из MutableMapping) создаётся из энвайромента в момент инициализации. Функция putenv() самостоятельно его не изменяет. В тоже время, когда вы создаёте или изменяете ключ в os.environ, автоматически вызывается putenv() в методе __setitem__(). То есть, технически putenv() всё делает верно, но в os.environ это не отражается. Можно проверить так: >>> os.putenv('MYVAR', '123') >>> os.system('python -c "import os;print(os.getenv(\'MYVAR\'))"') 123 Я объявил переменную в текущем процессе и вызвал дочерний процесс, который её унаследовал и получил в составе os.environ. Аналогично при удалении переменной вызывается еще одна built-in функция unsetenv(), удаляющая переменную из системы. Итого ▫️ Удобней всего явно обновлять переменные через os.environ ▫️ Есть способ неявно создать/удалить переменную через putenv/unsetenv, что не повлияет на os.environ но изменит энвайромент и передаст изменения сабпроцессам. Но так лучше не делать! ▫️os.environ это просто обертка для built-in функций putenv() и unsetenv(). #basic

Peru🇵🇪 Impressive natural masterpiece - the Rainbow Mountains in the Cusco region. ⛰🌈 The colorful layers of these mountains were formed millions of years ago from red sandstone, which, under the influence of climatic conditions, underground water, and mineral impurities, became stained with yellow, green, white, and other colors. #Peru @voyage

Peru🇵🇪 A walk with a magnificent view of Machu Picchu. Machu Picchu is a legendary city nestled in the heart of the Andes at an altitude of 2400 meters. It is an ancient Inca settlement located between two mountain peaks. 🏔 When tourists gaze at the ruins of the city of Machu Picchu, which stand out dramatically among the jungle-covered mountain peaks and steep slopes, and the terraces descending into the valley, their breath is taken away. #Peru @voyage

The right to die #video#Peru Ana Estrada is confined to bed most of the time and can breathe only with a respirator. She lives with polymyositis, a rare muscle disease with no cure. Since 2016, Ana has been writing a blog called ‘Ana seeks a dignified death’. In addition, she started a legal battle to decide to end her life ‘when the time comes’. Assisted death is illegal in her country of Peru. Peru is primarily a Catholic country, where euthanasia is prohibited alongside same-sex marriage and abortion. However, in 2021 a court ruled in favour of Ana and cleared anyone assisting in her death of criminal charges. Ana says she would decide to die when she could no longer write her blog. On this day in 2000, the Dutch lower house of parliament voted to legalise euthanasia. Thus, the Netherlands became the first country that allowed mercy killings. Euthanasia is also legal in Spain, Belgium, Luxembourg, Canada and Colombia. Follow: https://t.me/rtdocumentary

#video#Peru Hundreds of thousands of Peruvian women were forcibly sterilised between 1996-2000 as part of President Alberto Fujimori’s family planning programme. The initiative was launched to reduce poverty and cut birth rates among the poor. While it was supposed to be consensual, women involved in the programme say otherwise. Most of the victims came from poor indigenous communities. Josefa was at home when nurses came and forced her to go to the hospital. She still recalls waking up after the procedure and seeing other women crying out their husbands’ names in pain. In the following years, Josefa suffered from infections and cancer. Decades later, Josefa and others are still seeking justice through a class action suit against the ex-president. Follow: https://t.me/rtdocumentary
