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

🚀 Allwinner Technology Projects Significant Profit Growth for Q1 2026 Allwinner Technology has announced its financial projections for the first quarter of 2026, expecting net profits attributable to shareholders to range between 1.95 billion yuan and 2.2 billion yuan. According to Jin10, this represents a year-on-year increase of 112.99% to 140.30%. Excluding non-recurring gains and losses, net profits are projected to be between 1.9 billion yuan and 2.16 billion yuan, marking a growth of 238.21% to 284.49% compared to the same period last year. During the reporting period, the company adjusted its product sales prices in response to rising costs of upstream raw materials and packaging. Additionally, Allwinner Technology has been actively expanding its product lines and promoting the mass production of new products. The anticipation of price increases has also led downstream customers to increase their stockpiling. These factors have contributed to an approximate 45% year-on-year growth in operating revenue, which in turn has driven the increase in net profits. #AllwinnerTechnology#ProfitGrowth#Q12026#FinancialProjections#RevenueIncrease#NetProfit#TechnologyIndustry#BusinessGrowth

🚀 Global PC Shipments Expected to Rise by 3.2% in Q1 2026, Omdia Reports According to Jin10, Omdia's latest research indicates that the total shipments of desktops, laptops, and workstations are projected to increase by 3.2% year-on-year in the first quarter of 2026, reaching 64.8 million units. Among these, laptop shipments, including mobile workstations, are expected to see a slight year-on-year growth of 2.6%, reaching 50.8 million units. Desktop shipments, including desktop workstations, are anticipated to perform slightly better, with a year-on-year growth of 5.4%, reaching 14 million units. The growth is primarily driven by manufacturers and channel partners pulling in orders ahead of the widely expected rise in component costs. Additionally, the ongoing Windows 10 replacement cycle continues to drive corporate budget updates, and the concentrated product releases by Windows OEMs and Apple during the spring season are also contributing factors. #PCShipments#TechIndustry#LaptopGrowth#DesktopGrowth#OmdiaReport#Q12026#GlobalMarket#ITHardware#WindowsUpgrade#AppleRelease
