Produktbeschreibung

If you've mastered Python's fundamentals, you're ready to start using it to get real work done. Programming Python will show you how, with in-depth tutorials on the language's primary application domains: system administration, GUIs, and the Web. You'll also explore how Python is used in databases, networking, front-end scripting layers, text processing, and more. This book focuses on commonly used tools and libraries to give you a comprehensive understanding of Pythons many roles in practical, real-world programming.You'll learn language syntax and programming techniques in a clear and concise manner, with lots of examples that illustrate both correct usage and common idioms. Completely updated for version 3.x, Programming Python also delves into the language as a software development tool, with many code examples scaled specifically for that purpose.Topics include:Quick Python tour: Build a simple demo that includes data representation, object-oriented programming, object persistence, GUIs, and website basicsSystem programming: Explore system interface tools and techniques for command-line scripting, processing files and folders, running programs in parallel, and moreGUI programming: Learn to use Pythons tkinter widget libraryInternet programming: Access client-side network protocols and email tools, use CGI scripts, and learn website implementation techniquesMore ways to apply Python: Implement data structures, parse text-based information, interface with databases, and extend and embed Python

Rezensionen

"Programming Python von Mark Lutz [ist] so etwas wie meine Bibel der Python-Programmierung. Das Buch ist ab der zweiten Auflage nicht mehr für Anfänger geeignet, dieser Teil wurde in ein eigenes Buch ausgelagert. Doch auch wenn ich die Entscheidung bedauert habe, die Schwarte ist über 1.250 Seiten fett, da paßte das Anfänger-Tutorial vermutlich wirklich nicht mehr hinein. Ansonsten behandelt Mark Lutz hier wirklich alles, was man über Python wissen muß und das auf eine witzige und kurzweilige Art. Die erste Auflage habe ich im Büro deponiert, die zweite Auflage des Wälzers liegt immer ständig griffbereit neben meinem Schreibtisch zu Hause." -- Jörg Kantel, Schockwellenreiter.de, August 2006

"Ein wahrhaft umfassendes Handbuch! Das Buch ist schlichtweg DAS Referenzwerk zu Python - unübertroffen!! " -- www.php-nuke.de, April 2011
