问题
For nodejs there seems to be a very straightforward way to list all used modules and their licenses. Why is there no similar tool for python?
What I've found so far is pip-licenses which is pretty intuitive but has the flaw that it outputs all installed pip modules and not just the ones I actually imported in an actual project.
Another option might be to write a script that first searches for imported modules in my scripts by using modulefinder and then iterates over that list using pkg_resources to get the licenses.
Isn't there an easier, cleaner way to do this? I'm sure this task has been done by thousands of coders all over the world before.
