As stated in the tutorial , each vertex has a unique number as its id, starting from 0 continuously to N-1, where N is the number of vertices in the graph. However, the id for a vertex p may change if one vertex prior to it was deleted from the graph. So what is the most efficient way to refer to p …

The name attribute is treated in a special way by the internals of the Python interface; in particular, the name attribute is indexed internally in a Python dict so looking up the ID of a node given its name attribute is an O(1) operation (on average). The index is invalidated if you mutate the grap…
