Python

Python at a glance

Python is one of the most widely used programming languages, behind automation, tooling and many server applications. The core team ships a new minor version yearly, each maintained with bug and security fixes for several years; security patches also cover the standard library.

For admins Python is often a runtime beneath an application, whose requirements set the version. Apply security fixes promptly by moving the Python version in servers, containers and CI. The end-of-life date of your minor version belongs in the calendar — after that, gaps stay open. Version managers (pyenv) and containers keep multiple Pythons in parallel; on updates, check the application and its packages (especially native extensions). Track system-Python and app-Python separately, and keep pip/dependencies audited for known vulnerabilities.
