VertexFrame drop_vertices

---

drop_vertices(self, predicate)

Delete rows that qualify.

Parameters:

predicate : function

UDF which evaluates a row (vertex) to a boolean; vertices that answer True are dropped from the Frame

Parameters:

predicate : UDF

UDF or lambda which takes a row argument and evaluates to a boolean value.

Examples

Given VertexFrame object my_vertex_frame accessing a graph with lots of data for the attributes of lions, tigers, and ligers. Get rid of the lions and tigers:

>>> my_vertex_frame.drop_vertices(lambda row: row.animal_type == "lion" or row.animal_type == "tiger")

Now the frame only has information about ligers.
