Re: [igraph] Problem installing python-igraph on Mac OS X / iBook G4

[Gabor Csardi]

Benjamin, there are a few features that are R specific and I think
the same it true for Python. Graphics is (obviously) different.
The R and Python interface handles vertex/edge sets and attributes
differently. But all the functionality in the C core should be
available in both R and Python. (Unless we make a mistake and forgot
something, but that would be a bug.)

Kamada-Kawai layout is included in Python, see
