Рассмотрим установку языка программирования на Windows Server 2012, хотя установка на Windows 7, Windows 10 будет типовой.
Итак, для установки нам потребуется дистрибутив Python версию которой выбираем и скачиваем по ссылке: https://www.python.org/downloads/
Закачиваем и устанавливаем .msi пакет:
Выбираем установку для всех пользователей:
Выбираем директорию для установки, я оставляю по умолчанию C:\Python27:
Далее по умолчанию нажимаем NEXT, NEXT до окончания установки:
Теперь необходимо проверить добавился ли путь для командной строки.
В диспетчере задач нажимаем Run new task:
Набираем cmd и жмем ENTER:
В окне терминала набираем python и жмем Enter, если выдаст информацию, то на этом инсталляция закончена.
У меня, как всегда, просто не получается и python выдает ошибку:
В этом же окне терминала набираем sysdm.cpl и попадаем в System Properties:
Теперь нужно зайти в закладку Advanced и нажать кнопку Environment Variables:
Редактируем Path, добавляем в конце через точку с запятой путь куда установили Python, у меня это выглядит так — ;C:\Python27:
Теперь пробуем прописать python, но сделать это нужно в новом окне терминала, который подтянет наши записи:
Вот теперь установка Python закончена и можно работать.
Hi all,
Note: not sure if the following fals under bug report or feature request, and either of these would fit, please let me know.
Metadata:
- Platform: Windows
- Area: installer/documentation (code base could be covered later)
- Issue type: request/documentation/PEP 11
Overview
As stated in doc/using/windows.rst, CPython supports a Windows release under extended support by Microsoft. As of Python 3.13 alpha 2, the earliest supported Windows version is 8.1, which went out of extended support in January 2023 (reference 1).
Change request:
In accordance with PEP 11 (reference 2), I suggest dropping Windows 8.1/Server 2012 R2 support in Python 3.13 milestone — that is, Windows 10 or later releases are supported. This is because Windows 8.1 (client) is not receiving extended security updates (ESU’s) — only Server 2012 R2 receives security updates if enterprise customers pay for annual licenses. As support for a server release is tied to client releases, people can say that Python core developers should drop both 8.1 and Server 2012 R2 together.
Suggested modifications:
- Edit Windows installer to refuse to run unless Windows kernel version is 10.0 or above.
- Edit the Python documentation to state Windows 10 as minimum requirement.
- Long-term: edit C API and other code to drop Windows 8.1 assumptions.
References:
- Windows 8.1 lifecycle: https://learn.microsoft.com/en-us/lifecycle/products/windows-81
- PEP 11: https://peps.python.org/pep-0011/
Thanks.
