[PYTHON] [Note] How to use virtualenv

What is virtualenv

A library that allows you to build and manage Python virtual environments. You can build and manage a virtual environment that is separated for each Python version and each project. As a result, it is possible to manage each virtual environment, and it is possible to avoid the problem that the libraries do not work due to the dependency between the libraries.

Create virtual environment

$ virtualenv <Project name>

Virtual environment activation

$ source /bin/activate
$ . /bin/activate

Disable virtual environment

$ deactivate
