It solves the “Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keeps your global site-packages directory clean and manageable. There is no limit to the number of Python programming environments you can set up. Each environment on your server is essentially a folder or directory with a few scripts inside of it that causes it to function as an environment. The same study found Python to be the most desired coding language among those who do not presently use it.
