So congratulations, you’ve made it to the end of unit one. You’re learned a lot of computer science already, you know what a program is, you’ve learned about variables, you’ve learned about expressions and grammars, you’ve learned about strings in Python. So now it’s time for you to work on homework one on your own. And that will check that you understood everything from this class and prepare you to get started on unit two. And we’re well on our way towards learning a lot of computer science, as well as building our web crawler and then building our search engine.
