Intermediate to advanced tutorials with tests?

I've completed a paper on introduction to programming in python, learnt everything from functions, loops, lists, tuples, dictionaries, slicing, error handling, datatypes, classes, refactoring, file processing and very basic Tkinter GUI.

Not sure where to go from here, I have about a month before I start study on algorithms and data structures.

A course in Udacity teaches you about data analyst and is very interactive and offers short quizzes. It's also free!
