In Activity 4, we're teaching Magpie to respond to phrases, rather than just keywords. Statements like "I like CodeHS," "I like programming," "I like popsicles" all have the form of "I like x." A response to this could be "What do you like about x?" Exploration The Magpie class in the starter code here has revisions to handle phrases like this. Test Magpie by telling it "I want to build a robot," "Do you like me?" and "You confuse me." Exercises 1. Change the code so the response to "I want x" is "Would you really be happy if you had x?" 2. Change the code so the response to "1 x you" is "Why do you x me?" Then, find an example of a statement that doesn't make sense with this response. How could you improve it? Extra Credit Try adding a new keyphrase structure to Magpie. Here are some examples: -"Have you x?" -> "I haven't x, have you?" - "I'm going to x." -> "Good luck with x ! It sounds fun."
