Python packages can be installed:
/usr/lib/python3 if they were installed through the distribution’s package manager (apt, dnf…)$HOME/.local/lib/python3.xx if they were installed through pip (not running as the superuser)One may not want to cause changes to their system by installing Python packages in either of these two locations; instead, they can use self-contained virtual environments.
$ python3 -m venv myenv # Create the environment
$ source myenv/bin/activate # Enter the environment
$ (myenv) pip list # Notice the prompt changed
$ deactivate # Leave the environment, back to "normal"
$ pip list # Will show a different list of packages
