predicatecallable

The condition you want to evaluate. The callable takes 3 parameters: the identifier of the first vertex, the identifier of the second vertex, and the edge attributes, and should return True or False.

databool, optional

If True, yield the vertex attributes in addition ot the vertex identifiers.

Yields:

tuple[int, int] | tuple[tuple[int, int], dict[str, Any]]

If data is False, the next edge as a (u, v) tuple. If data is True, the next edge as a (u, v, data) tuple.
