Hi!
I'm having problems wrapping my head around this behaviour:
g = gt.Graph() g.add_vertex() g.vp['name_num'] = g.new_vp('object') print(g.vp.name_num[0]) # None g.vp.name_num[0] = [('a', 1)] print(g.vp.name_num[0]) # [('a', 1)] g.vp.name_num[0] = g.vp.name_num[0].append(('b', 2)) print(g.vp.name_num[0]) # None

This is perfectly normal and expected behavior, since the append() method returns None, which you are assigning to the property value.
