TIL: installed packages in Python – list, and show

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?

pip list

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.





List my packages:

# pip list
