Prior experience: Programming in Python for 3 years.
Manages to teach you quite a bit of Python in the short span of a few weeks.
Also learned about python modules, specifically ones that allow you to communicate with the browser (necessary for a search engine).
The forums (as always with Udacity courses) are excellent and the projects made by other students were amazing to see.
Got to know how a search engine works.
Is more like "An Introduction to programming with Python" although it does touch on a few basic computer science topics.
Take the course if you want to learn Python/how to make a search engine, but if you want a true introduction to computer science, you just might have to look elsewhere.
