'Graph' object has no attribute 'nodes_iter' in networkx module python

I have the below function in python2.7 using networkx module which produces the error. 

for H in networkx.connected_component_subgraphs(G):
    bestScore = -1.0
    for n, d in H.nodes_iter(data=True):
        if d['Score'] > bestScore:
            bestScore = d['Score']
            bestSV = n
    if bestSV is not None:
        selectedSVs.add(bestSV)

Error:

Traceback (most recent call last):
File "cnvClassifier.py", line 128, in <module>
for n, d in H.nodes_iter(data=True):
AttributeError: 'Graph' object has no attribute 'nodes_iter'

Does anybody have any idea what has been wrong?

You are probably using the pre-release version of networkx-2.0 which has removed the nodes_iter() method and now provides the the nodes() method with the same functionality. See this for details on the networkx-2.0 changes.

Just in case the link changes again, I'm going to post the actual solution here for future reference.

From NetworkX 2.0 forward, you should change the following line of code from: 

for n, d in H.nodes_iter(data=True):

to:

for n, d in list(H.nodes(data=True)):
