Managing Python Virtual Environments with pyenv
When using Python, you’ll encounter various version environments. First, distributions like RedHat and Debian have their own system Python installed, and you can also use Python built from source on a per-account basis as needed. Python has major syntax and built-in library differences between 2.x and 3.x versions, and minor versions can have different behaviors or implementations in some features - a free but sometimes risky situation. Of course, if you only operate one project on a single system and the version will never change, you may not need to worry about this. However, generally, a single system can have various Python projects, and these may often be implemented based on different Python versions. If you reduce cohesion between projects through dependency isolation, individual projects don’t need to worry about other environments. ...
