Setting Python Virtual Enverionment With Pyenv.

Even for someone who will use python in only one everionment(in your local as global), you don't need to install Python from Python official Installer.

Acutally, I think you better install python using Pyenv and set your local version of Python instead of installing directly from Python official Installer. This is because you can easily change your python evironment when you suddenly need to seperate Python environment.

If you Installed Python by official installer, you should Install Pyenv(or something like Pyenv) then. (Of course, It is also OK)

This is good reference for setting your Python virtual enverionment and global Python version in your local Using Pyenv.
