Randomly Implemented Virtual Environment Functions

This function randomly selects from predefined virtual environment related packages and implements a function related to the selected package. Here, the `virtualenvwrapper` package is selected, and a function to list all virtual environments is implemented.

Technology Stack : virtualenvwrapper, Python

Code Type : Function

Code Difficulty : Intermediate
