If your Python project has a very short list of required packages (in requirements, pipfile, etc), it’s easy to see all packages you have. But on large projects, the dependencies can run pretty long, not to mention the dependencies for the required packages. And what about learning more about those dependencies?
Will list all installed packages
pip show <package_name>
Will show information about installed packages and if you’re lucky, what other package requires that dependency
And, of course,
pip -h will show all other pip options.
