Yes. I think comparison is possible and important. Of course dependencies are handles in every language a bit differently. But on the other side they all do the same, more or less. The differences are more on the client side.

PIP is a good tool. But in my opinion the definition of dependencies shouldn't be in setup.py file. Because it's too easy to execute random code in a setup.py. A JSON file is the better choice for a project file, in my opinion.
