This codes gives correct output in my system but submitting it shows Restricted Function.
Plz help...

import Queue

to_explore=Queue.Queue()

    dic[root]=0
    to_explore.put(root)

if 'Isenbaev' in graph:
    BFS('Isenbaev')
    for i in graph:
        if i not in dic:
            dic[i]='undefined'
    for i in sorted(dic):
        print i,dic[i]
else:
    for i in sorted(graph):
        print i,"undefined"

Don`t the queue module starts with lowercase letter?
Looks like: from queue(module) import Queue(function)
Actually, I have pretty similar code and always have runtime error on the very first test
