HalfEdge.vertices_where_predicate(predicate, data=False)[source]

Get vertices for which a certain condition or set of conditions is true using a lambda function.

Parameters

  • predicate (callable) – The condition you want to evaluate. The callable takes 2 parameters: key, attr and should return True or False.

  • data (bool, optional) – Yield the vertices and their data attributes. Default is False.

Yields

  • key (hashable) – The next vertex that matches the condition.

  • 2-tuple – The next vertex and its attributes, if data=True.
