<p>A virtual environment is a way to have multiple, parallel instances of the Python interpreter, each with different package sets and different configurations.
Each virtual environment contains a discrete copy of the Python interpreter, including copies of its support utilities. It also protects your system in case of problems with the packages.</p>
