Hi, What you want is achieved by the Python built-in filter() function: https://docs.python.org/3.8/library/functions.html#filter Best, Tiago Am 30.10.19 um 14:45 schrieb Gerion Entrup:
Hi,
I often have this pattern in Python:
``` for vertex in mygraph.vertices(): if not mygraph.vp.is_foo[vertex]: continue do_stuff_that_uses_all_vertices() ```
`is_foo` is a boolean property.
I know that there a vertex filters and GraphViews but in the loop body I need access to all vertices. Only the iterator should be filtered.
Is there a way to specify a vertex filter only in the vertices iterator? Something like: ``` for vertex in mygraph.vertices(vfilt=mygraph.vp.is_foo): do_stuff_that_uses_all_vertices() ```
Of course, this would be nice in all iterators (edges(), out_edges(), ...) ;).
Best, Gerion
