Isolating project dependencies.
WHAT THE PROBLEM IS
Two projects needing different versions of the same library.
Installed globally, they conflict.
WHAT A VIRTUAL ENVIRONMENT IS
An isolated set of installed packages for one project.
WHY IT MATTERS
Each project has exactly what it needs Upgrading one project does not break another You can reproduce the environment elsewhere
WHEN TO CREATE ONE
For every project, without exception.
HOW IT WORKS
You create it, activate it, and install packages into it.
While active, Python and package commands use that environment.
WHAT TO DO
Create it inside the project folder Exclude it from version control Record dependencies separately
WHAT NOT TO DO
Install project packages globally Copy an environment between machines
WHY NOT COPY
Environments contain paths specific to where they were created.
Recreate from the dependency file instead.
ON YOUR HOSTING
cPanel's Python application feature creates and manages a virtual environment for you.
