Many successful programmers know more than just a computer language. They also know how to think about solving problems. They use "computational thinking": breaking a problem down into segments that lend themselves to technical solutions. Code Clinic is a series of six courses where lynda.com authors solve the same problems using different programming languages. Here, Barron Stone works with Python.

Each month, Barron will introduce a new challenge and provide an overview of his solution in Python, explaining how he broke the problem up into logical components, and revealing the difficulties he encountered. Challenges will include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.

Visit other courses in the series to see how to solve the exact same challenge in languages like C#, C++, Java, PHP, and Ruby. And check back every month for new challenges.

- Hello, and welcome to Code Clinic. My name is Baron Stone. Code Clinic is a monthly course where a unique problem is introduced to a collection of lynda.com authors. In response, each author will create a solution using their programming language of choice. You can learn several things from Code Clinic. Different approaches to solving a problem, the pros and cons of different languages, and some tips and tricks to incorporate into your own coding practices. This month the problem is to create a musical instrument controlled by the mouse.

If you move the mouse up and down it should change the pitch of the instrument and if you move the mouse side-to-side it'll change the volume. The instrument is silent until we click and hold one of the mouse buttons and letting go of the mouse button turns off the musical tone. It's a simple request, but because it requires access to the mouse it may be difficult or impossible in some languages. In all cases, we'll explore some of the ways to solve the problem and learn why they might not work. Thomas Edison observed that, "Negative results "are just what I want.

"They're just as valuable to me as positive results "and I can never find the thing that does the job the best "until I find the ones that don't." You may want to take some time and solve the problem yourself and in the next videos I'll explain how I answered this challenge.
