Gephi gist to delete all nodes with specific attribute (Modularity class)

gephi_del.py

# Delete some nodes from Gephi graph
# run from Gephi scripting console as execfile("/Fullpath/gephi_del.py") or 
# execfile("C:\\Fullpath\\gephi_del.py") for windows

# Delete all nodes from Modularity class 5
subgraph = g.filter(modularity_class == 5) # first filter those out to a new subgraph
# Then iterate and delete
for v in subgraph.nodes:
	print v.label # just testing which node is accessed
	del v
  
# Now it should work!

This will not work, as soon you put the functionality inside of a method.
Please include a solution, where 'del' actually is located inside of a method an works well.

You are right it is strange with the method, even though I could print v.label, del v has no real effect. I can speculate that ir works on a copy of the nodes...
