Creating a virtual Python environment

The virtual environment in Python allows you to isolate projects from each other for more convenient management, projects placed in a virtual environment can use different modules and dependencies, including their different versions, which makes the administration of such projects very convenient.

To create a virtual Python environment, log in with SSH or WEB-SSH .

Go to the directory in which you want to create a virtual environment

 cd www/py-projects/

Create the virtual environment using the command for the required Python version . venv-project is an arbitrary project name, do not forget to change it, and as a result of executing the command, a directory with this name will be created.

 /opt/alt/python37/bin/python3 -m virtualenv venv-project

Variant for Python 3.8

 /opt/alt/python38/bin/python3 -m venv venv-project

Activation of the virtual environment
