CCNA Official Exam Certification Library, Third Edition, is the newest edition of the all-time best-selling CCNA self-study preparation package. This comprehensive review and practice package is designed for the latest CCNA® 640-802 exams. The two books contained in this package, CCENT/CCNA ICND1 Official Exam Certification Guide, Second Edition, and CCNA ICND2 Official Exam Certification Guide, Second Edition, present complete reviews and a more challenging and realistic preparation experience. The books are updated to cover all the new 640-802 exam objectives, such as security, wireless, IPv6, and troubleshooting.

Please note that while this is the Third Edition of the Library, the two books inside are Second Editions. This is correct, and the editions align differently because of changes in the names of the exams, from the old INTRO and ICND to the new ICND1 and ICND2 formats.

First off, Learning Python shows the relationships among Python scripts and their interpreter (in a mostly platform-neutral way). Then, the authors address the mechanics of the language itself, providing illustrations of how Python conceives of numbers, strings, and other objects as well as the operators you use to work with them. Dictionaries, lists, tuples, and other data structures specific to Python receive plenty of attention including complete examples.

Authors Mark Lutz and David Ascher build on that fundamental information in their discussions of functions and modules, which evolve into coverage of namespaces, classes, and the object-oriented aspects of Python programming. There's also information on creating graphical user interfaces (GUIs) for Python applications with Tkinter.
