bash
curl https://pyenv.run | bash

  1. Add `pyenv` to your shell startup file (e.g., `.bashrc` or `.zshrc`):

bash
export PATH=”$HOME/.pyenv/bin:$PATH”
eval “$(pyenv init –path)”
eval “$(pyenv init -)”
eval “$(pyenv virtualenv-init -)”

  1. Restart your shell or run `source ~/.bashrc`.
  1. Install a specific Python version:

bash
pyenv install 3.x.x

  1. Set a global Python version:

bash
pyenv global 3.x.x

Comparison of Python Package Managers

When upgrading Python, managing packages can also be crucial. Here’s a comparison of popular Python package managers:
