Example text

Assuming you’ve harvested all of @user’s friendships and all of the friendships for these friendships (friends of friends), you can create a graph of the common friendships that exist for this entire network— whether or not @user is one of the nodes in the graph. There are many spins and variations that you could integrate into this example, and more types of analysis than could fill a small book. As you add more nodes to the graph and more heuristics to the graph construction algorithm, it only gets more interesting.

Once a suitable depth has been reached, the traversal terminates. A breadth-first traversal is easy to implement, and the neighbors for each node can be stored on disk and later analyzed as a graph. The two characteristics that govern the space complexity of a breadth-first traversal are the depth of the traversal and the average branching factor of each node in the graph. The number of followers for Twitter users varies wildly; all it takes to dramatically effect the average branching factor is a very popular follower, so it would be wise to set an upper threshold.

5 hours, which is a bit of a wait, but it’s still pretty amazing that you could harvest that much data in less than a business day. html) can be used to layer on some additional sugar to illustrate how you could ultimately create the get_friends_ids and get_followers_ids functions that you’ve really always wanted. Example 1-23 illustrates how to use make_twitter_request in the manner described to fetch some friends and followers ids. Example 1-23. argv[2]) if __name__ == '__main__': # Not authenticating lowers your rate limit to 150 requests per hr.
