The following is a series of exercises. Answers to all these exercises can be found in the Answers_to_Exercises_Chap10.ipynb Jupyter Notebook in this book’s GitHub repository:

1. The Zachary Karate Club is a well-known network in the field of network science, so much so that a copy of the network is stored in the NetworkX package and can be accessed via the karate_club_graph() function. Use this function to create the karate club graph and then use the community.greedy_modularity_communities function to identify the communities within the graph. You can assume that there are two communities, so you should look at how to use the cutoff and best_n parameters of the community.greedy_modularity_communities function to ensure that only two communities are found. Which nodes do you think are at the center of each of the two communities found?
2. Use the scale_free_graph function of the NetworkX package to create a scale-free graph with 10,000 nodes. Having generated...
