- Hello, and welcome to Code Clinic.…My name is Barron 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 combines two concepts,…Recursion and Accessing Data.…Recursion means to repeat something in a similar way.…
And, in this problem, our program will need…to be capable of recursively searching for image files…stored in directories inside of other directories…inside of other directories, and on…and on to an unknown level of depth.…JPEG files can contain additional…image data stored as EXIF or IPTC.…EXIF stands for Exchangeable Image File Format…and is a well-documented standard.…If you have a digital camera or have taken photos…with a newer cell phone camera,…
Barron introduce challenges and provides an overview of his solutions in Python. Challenges 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 challenges in languages like C#, C++, Java, PHP, and Ruby.
