We have a working tool built off of various packages in python. I am not sure how to cite these packages for a paper I am working on. How do I properly cite python packages? One of them have a way they ask us to cite them via a book. Most say nothing on citations that I can find. Is there a standard?
This link has the preferred citation method for scipy and it's related packages. If you aren't using one of these packages you could follow the style they use.
