class documentation

class Vertex:

View In Hierarchy

Class representing a single vertex in a graph.

The vertex is referenced by its index, so if the underlying graph changes, the semantics of the vertex object might change as well (if the vertex indices are altered in the original graph).

The attributes of the vertex can be accessed by using the vertex as a hash:

>>> v["color"] = "red"                  #doctest: +SKIP
>>> print(v["color"])                     #doctest: +SKIP
red

def update_attributes(E, **F):

Updates the attributes of the vertex from dict/iterable E and F.

If E has a keys() method, it does: for k in E: self[k] = E[k]. If E lacks a keys() method, it does: for (k, v) in E: self[k] = v. In either case, this is followed by: for k in F: self[k] = F[k].

This method thus behaves similarly to the update() method of Python dictionaries.
