Setting up python

If you are confused about how to setup different python environments in your system, here is how I do it.

1. Install pyenv : You do not want to use your default system python or mess around with it. pyenv will let you install different versions of python, setup a global python version or setup different versions of python for different projects.
   • pyenv install <version> -> installs a new version of python
   • pyenv global <version> -> sets an installed version as global python version
   • pyenv local <version> -> sets an installed version as local(to the directory) python version. Notice a .python-version file generated.
2. Setup and use a virtual environment.
   • python -m venv .venv -> create a new virtual environment
   • source .venv/bin/activate -> activate created virtual environment
