5: Python 3 Virtualenv(Command line Python scripting)

By default, virtualenv will use the pythonexecutable when it makes a new virtualenv, which means that it has the same version of Python as the system. In this case, we want to use python3 instead for our virtualenv. In order to do this, we pass the -p flag to thevirtualenv command, which will allow us to change the Python interpreter that virtualenv uses.

In this case, we can type virtualenv -p /usr/bin/python3 python3 to use Python 3 instead of Python 2.

Instructions

Create a virtualenv called python3 in the /home/dq folder that uses Python 3.                                        /home/dq$ virtualenv -p /usr/bin/python3 python3                                 Running virtualenv with interpreter /usr/bin/python3                             Using base prefix '/usr'                                                         New python executable in /home/dq/python3/bin/python3                            Also creating executable in /home/dq/python3/bin/python                          Installing setuptools, pip, wheel...done.
