The included files are the exercises (and my solutions) from Exercism's Python Track. Each directory contains a README from Exercism describing the problem, a test file written by Exercism, and my solution file. The solution files are downloaded from Exericsm and come with pre-defined functions used by Exercism's test file to determine completeness. However, all other data in the solution files are my own work.
Feel free to check out my Exercism profile as well!
