Random Virtualenv Package Functionality

This function randomly selects a package from the virtualenv-related libraries and implements a basic feature based on the selected library. Depending on the selected library, the function can create a virtual environment, list all virtual environments, install ipykernel, or switch to a specified virtual environment.

Technology Stack : virtualenv, virtualenvwrapper, ipykernel, virtualfish, subprocess, random
