Managing Python using pyenv, virtualenv, and pyenv-virtualenv

Problem: You want to maintain multiple different versions of python and keep packages separated based on projects that you're working on.

Solution: Use the pyenv, virtualenv tools along with the pyenv-virutalenv plugin to manage multiple versions of python and seamlessly integrate them with your projects' virtual environments.

	# find filename on https://go.dev/dl/

	# sudo ./install_go.sh

	mkdir /tmp/downloads

	counter[t.charCodeAt(i) - 'a'.charCodeAt(0)]--
