Linux having multi-python virtual environment too ...

By setting up the python2/python3: pip package manager.

I'd install the virtualenv-wrapper package, then create virtual environment in python3.

It was working on Windows only, but now Linux too, just adding some bash script in the ".bashrc" file in the Linux system.

For quick setup - install python and pip3, if I haven't installed or checking at least by which command in Linux (Arch, Debian, Fedora or ubuntu ) for my PC.

sudo apt update
sudo apt install python3-pip
sudo apt install python3-virtualenvwrapper

sudo apt update 
sudo nano ~/.bashrc

By adding these scripts by scrolling below at the end of the ".bashrc" file.

export VIRTUALENVWRAPPER_PYTHON='/usr/bin/python3.x'
export WORK_ON='/home/linux_name/python_environment'(.virtualenv folder)
source /usr/share/virtualenvwrapper/virtualenvwrapper.sh

where,

python3.x = python3.8, python3.9 or python2.10, etc.

python_environment = any folder name in the home directory

linux_name = computer name for Linux system, like in my case "hackout" is a name of Linux.

sudo apt update; sudo apt upgrade

if you want to know, then see this demo video.

finds some helpful commands.

lsvirtualenv
List all of the environments stored in WORKON_HOME.

mkvirtualenv <name>
create the environment.

rmvirtualenv <name>
Remove the environment.

workon <name>
If is specified, activate the environment named (change the working virtualenv to ). If a project directory has been defined, we will change it. If no argument is specified, list the available environments. One can pass additional option -c after virtualenv name to cd to virtualenv directory if no project dir is set.

deactivate
Deactivate the working virtualenv and switch back to the default system Python.

add2virtualenv <full or relative path>

Yeah! I can do machine learning and deep learning projects, and most important make a remarkable website with Django or flask in a python virtual environment customized.

Okay, here is a short note, about how I got this lazy idea and where I find it, then read the pypi.org sub-projects.

Peace GUYS

Happy Hacking !!
