Choosing all four of the links in the section The FEniCS API Documentation, and searching for errornorm , I find nothing.

Just to add to Dokken, I would recommend using Visual Studio Code (https://code.visualstudio.com/). The python extension module enables you to view the documentation of the function in place and can be quite useful.

@Golam

degree = int(sys.argv[1])

This should help you with understanding how to pass command line arguments in your code.

I cannot install scitools to work with the example in the fenics book, vcp2D.py .

I don’t think this is actively maintained/developed.

What is the proper way to look for documentation for dolfin?

The best way I would say is the source directory; see e.g. errornorm. A lot of the unchanged functions can also be looked up in dolfin-2017.2.0 release, though some things would have changed and you should read the change log for those.
