Outline:
According to an explanation by linuxize.com, Python virtual environment is a self-contained directory tree that includes a Python installation and number of additional packages. The main purpose of Python virtual environments is to create an isolated environment for different Python projects. This way you can install a specific version of a module on a per project basis without worrying that it will affect your other Python projects.
python3 -VThe output should be like this:
Python 3.8.10venv module.You can install that module by type this command on the terminal:
sudo apt install python3-venvpython3 -m venv my-project-envThe above command will create a directory called
my-project-env which contains a copy of the python supporting files for the virtual environment.source my-project-env/bin/activateAfter that, you might notice that there is something unique in your terminal. And if it do so, then your virtual environment is ready to go.
To test it, you can type the following command in the terminal:
pip install numpyThe above command will install python numpy package and the above package can only used if you activate the virtual environment.
