Aha - yeah. Sorry, using arrays works, but not lists. (important to know, though)

Thanks Tiago!
Let me just point out that the part
mask.a = g.degree_property_map("out").a > 4
will (if you are using python 2.x) not give you what you most likely
would like to have, namely a list of boolean values containing the results of the element wise comparisons of elements g.degree_property_map("out").a[i]>4. Instead, for some strange reason, you'll simply get the *value* True back, writing True to all elements in mask.a ... instead, it seems to me, the only (fastest) way to do it is to use map
mask.a = map(lambda(x): x > 4, g.degree_property_map("out").a)
.... so be careful.
Are you sure?
I get the following with python 2 and numpy 1.7.1:
In [4]: arange(10) Out[4]: array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]) In [5]: arange(10) > 2 Out[5]: array([False, False, False, True, True, True, True, True,True, True], dtype=bool)
Cheers, Tiago
