Data type of attributes in igraph, python

Question

In order to speed up my code, I am using Cython. I was wondering whether it is possible to fix the type of attributes for a Graph object in igraph?

Answer 1

Attributes in igraph are returning PyObject s so no, you cannot type them in Cython.

However, depending on your use case, it may be useful to pre-assign the attributes to a typed c++ vector or a C array, then work on this vector/array.
