pyenv

pyenv is a good tool to manage python versions. It can be used to install multiple versions of python and switch between them. I prefer to use python version manager because I prefer always use latest version of python. and easy to mange pip packages.

1. what pyenv dependencies need for debian/ubuntu? (minimal install)

   sudo apt install git gcc make zlib1g-dev libssl-dev libbz2-dev libncurses5-dev libncursesw5-dev libffi-dev libreadline-dev libsqlite3-dev liblzma-dev
   

2. install pyenv itself https://github.com/pyenv/pyenv?tab=readme-ov-file#automatic-installer curl https://pyenv.run | bash

3. setup shell refer this.

   echo '# pyenv' >> ~/.bashrc
   echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
   echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
   echo 'eval "$(pyenv init -)"' >> ~/.bashrc
   

4. finall thing is install specific python version, set as global pyenv install 3.12.2 pyenv global 3.12.2
