There are multiple ways of creating that, today we will create one using mkvirtualenv command.

To use the mkvirtualenv command you need to have virtualenvwrapper installed which is nothing but a set of python extension commands.
Make sure you have pip installed.
$ sudo apt-get install python3-pip
$ sudo pip3 install virtualenvwrapper
Open bashrc by –
$ sudo gedit ~/.bashrc
After opening it, add the following lines to it :
export WORKON_HOME=$HOME/.virtualenvs export PROJECT_HOME=$HOME/Devel source /usr/local/bin/virtualenvwrapper.sh
Save the bashrc file.
Using mkvirtualenv command
Now let us use it,
The syntax is :
$ mkvirtualenv venv_name
If you want to work on another version of python, try this :
$ mkvirtualenv -p python3.x venv_name $(venv_name) // You will see something like this
Note: You can use any version in place of x.
To work on an existing virtual environment,
$ workon venv_name
To get out of the virtual environment –
