.python Version -
Here's a brief history of major Python versions:
To manage multiple Python versions on your system:
system
Tells pyenv to skip its own shims and use the system Python (e.g., /usr/bin/python). Dangerous for production but sometimes used for system scripts.
When you run python inside a directory, pyenv looks for a .python-version file in the current directory, then parent directories, until it reaches your home folder. If none exists, it falls back to the global version (set via pyenv global).
3.11.5
Use this for production projects. It guarantees bytecode compatibility. .python version
If you want to know which version of Python is currently active on your system, use the command line interface (CLI).
Standard Command:
python --version
# OR
python -V
If you have multiple versions installed (e.g., Python 2 and 3):
python2 --version
python3 --version
Expected Output:
Python 3.11.4
Python 3 follows a predictable release cycle: a new version every 12 months, followed by about 5 years of bugfix and security updates. Here’s the current status:
| Version | Release Date | Bugfix Support Ends | Security Support Ends | |---------|--------------|----------------------|------------------------| | 3.9 | Oct 2020 | May 2023 | Oct 2025 (soon) | | 3.10 | Oct 2021 | May 2024 | Oct 2026 | | 3.11 | Oct 2022 | May 2025 | Oct 2027 | | 3.12 | Oct 2023 | May 2026 | Oct 2028 | | 3.13 | Oct 2024 | May 2027 | Oct 2029 | | 3.14 (dev) | Oct 2025 | May 2028 | Oct 2030 |
Table based on PEP 602 & PEP 619. Full details at Python.org.
Your safe bets today:
Avoid 3.9 and earlier unless you absolutely must support a legacy dependency.
If you’ve ever typed python --version into a terminal, you’ve opened a tiny door into one of the most fascinating, frustrating, and successful stories in software history.
Python’s version history isn’t just a list of numbers. It’s a drama. A soap opera with characters like “the GIL,” “the print function,” and “the walrus operator.” It has heroes (Guido van Rossum, the original “Benevolent Dictator for Life”), villains (backward incompatibility!), and cliffhangers (will they finally speed it up?).
Let’s unwrap the strange timeline of Python versions. Here's a brief history of major Python versions:
