# Your new Python version python3.12 --version python3 --version Updating pip and Virtual Environments After installing a new Python, update its pip:
Python is constantly evolving, with new versions bringing performance improvements, security patches, and exciting features. If you're a Linux user, keeping Python updated is essential, but the process isn't always straightforward—especially since your system may depend on a specific Python version to run critical components.
Ubuntu/Debian:
python3.12 --version pyenv lets you install and switch between multiple Python versions per project without touching system Python. Install pyenv # Install dependencies (same as source compilation) # Then run pyenv installer curl https://pyenv.run | bash Add to your ~/.bashrc (or ~/.zshrc ):
export PATH="$HOME/.pyenv/bin:$PATH" eval "$(pyenv init -)" eval "$(pyenv virtualenv-init -)" # optional, but useful Restart your shell. # List all installable versions pyenv install --list Install a new version (e.g., 3.12.2) pyenv install 3.12.2 Set it globally (for your user only) pyenv global 3.12.2 Or set per project directory cd my_project pyenv local 3.12.2 Verify python --version how to update python on linux
Remember: there's no single "latest Python" command across all distros. Choose the approach that fits your workflow, and always verify your installation before running critical scripts. Updated April 2026 – Works with Python 3.12+ and all major Linux distributions.
With pyenv , python and pip automatically point to your chosen version without affecting system tools. After any method, check: # Your new Python version python3
