[igraph] Modularity function on python version

[Simone Caschili]

Hello,

I'm using modularity function on igraph  python version. I would get a value of modularity for my graph g that is a weighted graph while I would pass an a priori membership. Thus, in order to get what i need, i have built a list  that represents my membership, it is like:

memb=[0,0,0,0,1,1,1,1,1] 

I would just split my graph into two communities. Edge's weights  are also stored in a list like:

weighs=[2,3,89,32,1,2,4]

When I run my code I get this error:

>Traceback (most recent call last):
> File "1.py", line 120, in ?
>    print g.modularity(memb,weights)
>TypeError: modularity() takes exactly 2 arguments (3 given)

Since I've tried to use only membership or weights, the code works but it doesn't solve my issue because i need a "weighed" modularity calculated on a certain membership. 

Could anyone help me?
Thank you
