PySchools and CodingBat
As an effort to practice python, I have been doing CodingBat and PySchools challenges.
Finally, today I finished all the challenges, totally there were more than 250 in these two combined. I don’t know how justified is that, but I am now in the first place of PySchools worldwide ranking )
The guy who made CodingBat is Nick Parlante, the same person who made the Google Python Class videos which were my gateway into learning python. He is making other cool things too, for example this.
