Python Versions in Debian Linux

 Python Versions in Debian Linux

Debian Linux distributions typically include specific Python versions, with newer Debian releases generally featuring more recent Python 3 versions.  

The default Python version often refers to Python 3, while older Python 2 versions might still be available for compatibility with legacy systems.

 

Here are some examples of Python versions found in different Debian releases:

  

Debian Trixie: Python 3.13

 

Debian Bookworm: Python 3.11

 

Debian Bullseye: Python 3.9 (with minimal support for Python 2.7)

 

Debian Buster: Python 2.7, Python 3.7

 

Debian Stretch: Python 2.7, Python 3.5

 

It is possible to install specific Python versions on Debian, even if they are not the default for a particular release, using tools like apt or by compiling from source.

 

Python 3.9

 

Python 3.9 is a specific, stable version of the Python programming language, released in October 2020, known for introducing significant quality-of-life improvements.

 

In essence, Python 3.9 was a significant update that streamlined common tasks, improved developer experience with typing and syntax, and laid groundwork for future versions, even as it concluded its main support phase. 

 

 Although it's a mature version, Python 3.9 reached its official end-of-life (EOL) in late 2025, meaning it no longer receives standard support but remains in use, especially in stable environments like Red Hat Enterprise Linux (RHEL).

 

Red Hat is resistant to change and that is why I am totally dissociated from Redhat and Fedora.
