[igraph] degree distribution for bipartite network

[Simone Gabbriellini]

Hello List,

how can I find the degree distribution for separate sets of nodes? In R I do 
something like:

deg<-degree(g)[V(g)$type==FALSE]
dd<-as.numeric(table(deg))/sum(as.numeric(table(deg)))

Is it possible in python to find the degree distribution conditioned on a 
node's attribute value?

many thanks,
Simone
