Why Take This Course

You’ll learn the programming language Python, and you’ll explore foundational concepts in computer science. Most importantly, you’ll start thinking like a software engineer by solving interesting problems (how to build a web crawler or a social network) using computer programming.

This course is a first step into the world of computer science, and whether you want to become a software engineer, or collaborate with software engineers, this course is for you. You’ll be prepared for intermediate-level computer science classes when you’ve mastered the concepts covered in this course.

Build a Search Engine

Throughout this course, you’ll build a search engine by learning about and producing key search engine components including a crawler, an index and a page rank algorithm. As you build these pieces, you’ll be learning about and practicing computer science skills that will ready you for intermediate level computer science courses.

Build a Social Network

At the end of the course we will give you a set of relationships (i.e. strings of phrases like “Dave likes Andy, Kathleen and Kristy”) and you will use your new computer science skills to organize these relationships into a social network. With your new social network, you can explore relationships and gain insight into how you fit into your own social networks.
