Python Versions and Dependencies Made Easy
summary
Concrete workflow and tools: use pyenv global/local/shell to install and switch real Python interpreters rather than touching system Python, create per-project environments with venv or virtualenvwrapper stored in ~/.virtualenv so pip stops overwriting versions, and install CLI tools with pipx installs packages into isolated venvs so global tools never clobber each other. Demonstrations include installing specific Python versions, showing automatic local switching, pipx install/upgrade/uninstall and pipx inject. For production, pin resolved deps with pip-tools (pip-compile) and bake into Docker or a sealed venv.
