Problem
Part I: A use profile provides a rich source of information to study twitter users. Given a list of user's screen names, write a crawler to display this users' profile infor- mation. You should get the following information for any existing twitter user:
User name:
Screen name:
User ID:
Location:
User description:
The number of followers:
The number of friends:
The number of tweets (i.e., statuses):
User URL:
Part II: There are two types of connection between users: follower and friend. Friendship is bidirectional while following is one direction. In the following figure, Amy and Peter are friends (meaning that they follow each other), Bob is following Amy (so Bob is Amy's follower), and Amy follows Sophia.
Given a list of user's screen names (any existing names), write a crawler to collect the users' social network information (i.e., display friends and the first 20 followers). Note that friends are bidirectional (e.g., Amy and Peter are friends as they follow each other).
