* Already know Python but want to learn more? A lot more? Dive into a variety of topics used in practice for real-world applications. * Covers regular expressions, Internet/network programming, GUIs, SQL/databases/ORMs, threading, and Web development. * Learn about contemporary development trends such as Google+, Twitter, MongoDB, OAuth, Python 3 migration, and Java/Jython. Presents brand new material on Django, Google App Engine, CSV/JSON/XML, and Microsoft Office. Includes Python 2 and 3 code samples to get you started right away! * Provides code snippets, interactive examples, and practical exercises to help build your Python skills. The Complete Developer's Guide to Python Python is an agile, robust, and expressive programming language that continues to build momentum. It combines the power of compiled languages with the simplicity and rapid development of scripting languages. In Core Python Applications Programming, Third Edition, leading Python developer and corporate trainer Wesley Chun helps you take your Python knowledge to the next level. This book has everything you need to become a versatile Python developer. You will be introduced to multiple areas of application development and gain knowledge that can be immediately applied to projects, and you will find code samples in both Python 2 and 3, including migration tips if that's on your roadmap too. Some snippets will even run unmodified on 2.x or 3.x. * Learn professional Python style, best practices, and good programming habits * Build clients and servers using TCP, UDP, XML-RPC, and be exposed to higher-level libraries like SocketServer and Twisted * Develop GUI applications using Tkinter and other available toolkits * Improve application performance by writing extensions in C/C++, or enhance I/O-bound code with multithreading * Discover SQL and relational databases, ORMs, and even non-relational (NonSQL) databases like MongoDB * Learn the basics of Web programming, including Web clients and servers, plus CGI and WSGI * Expose yourself to regular expressions and powerful text processing tools for creating and parsing CSV, JSON, and XML data * Interface with popular Microsoft Office applications such as Excel, PowerPoint, and Outlook using COM client programming * Dive deeper into Web development with the Django framework and cloud computing with Google App Engine * Explore Java programming with Jython, the way to run Python code on the JVM * Connect to Web services Yahoo! Finance to get stock quotes, or Yahoo! Mail, Gmail, and others to download or send e-mail * Jump into the social media craze by learning how to connect to the Twitter and Google+ networks Core Python Applications Programming, Third Edition, delivers *Broad coverage of a variety of areas of development used in real-world applications today *Powerful insights into current and best practices for the intermediate Python programmer *Dozens of code examples, from quick snippets to full-fledged applications *A variety of exercises at the end of every chapter to help hammer the concepts homePreface xv Acknowledgments xxvii About the Author xxxi Part I: General Application Topics 1 Chapter 1: Regular Expressions 2 1.1 Introduction/Motivation 3 1.2 Special Symbols and Characters 6 1.3 Regexes and Python 16 1.4 Some Regex Examples 36 1.5 A Longer Regex Example 41 1.6 Exercises 48 Chapter 2: Network Programming 53 2.1 Introduction 54 2.2 What Is Client/Server Architecture? 54 2.3 Sockets: Communication Endpoints 58 2.4 Network Programming in Python 61 2.5 The SocketServer Module 79 2.6 Introduction to the Twisted Framework 84 2.7 Related Modules 88 2.8 Exercises 89 Chapter 3: Internet Client Programming 94 3.1 What Are Internet Clients? 95 3.2 Transferring Files 96 3.3 Network News 104 3.4 E-Mail 114 3.5 Related Modules 146 3.6 Exercises 148 Chapter 4: Multithreaded Programming 156 4.1 Introduction/Motivation 157 4.2 Threads and Processes 158 4.3 Threads and Python 160 4.4 The thread Module 164 4.5 The threading Module 169 4.6 Comparing Single vs. Multithreaded Execution 180 4.7 Multithreading in Practice 182 4.8 Producer-Consumer Problem and the Queue/queue Module 202 4.9 Alternative Considerations to Threads 206 4.10 Related Modules 209 4.11 Exercises 210 Chapter 5: GUI Programming 213 5.1 Introduction 214 5.2 Tkinter and Python Programming 216 5.3 Tkinter Examples 221 5.4 A Brief Tour of Other GUIs 236 5.5 Related Modules and Other GUIs 247 5.6 Exercises 250 Chapter 6: Database Programming 253 6.1 Introduction 254 6.2 The Python DB-API 259 6.3 ORMs 289 6.4 Non-Relational Databases 309 6.5 Related References 316 6.6 Exercises 319 Chapter 7: Programming Microsoft Office 324 7.1 Introduction 325 7.2 COM Client Programming with Python 326 7.3 Introductory Examples 328 7.4 Intermediate Examples 338 7.5 Related Modules/Packages 357 7.6 Exercises 357 Chapter 8: Extending Python 364 8.1 Introduction/Motivation 365 8.2 Extending Python by Writing Extensions 368 8.3 Related Topics 384 8.4 Exercises 388 Part II: Web Development 389 Chapter 9: Web Clients and Servers 390 9.1 Introduction 391 9.2 Python Web Client Tools 396 9.3 Web Clients 410 9.4 Web (HTTP) Servers 428 9.5 Related Modules 433 9.6 Exercises 436 Chapter 10: Web Programming: CGI and WSGI 441 10.1 Introduction 442 10.2 Helping Web Servers Process Client Data 442 10.3 Building CGI Applications 446 10.4 Using Unicode with CGI 464 10.5 Advanced CGI 466 10.6 Introduction to WSGI 478 10.7 Real-World Web Development 487 10.8 Related Modules 488 10.9 Exercises 490 Chapter 11: Web Frameworks: Django 493 11.1 Introduction 494 11.2 Web Frameworks 494 11.3 Introduction to Django 496 11.4 Projects and Apps 501 11.5 Your "Hello World" Application (A Blog) 507 11.6 Creating a Model to Add Database Service 509 11.7 The Python Application Shell 514 11.8 The Django Administration App 518 11.9 Creating the Blog's User Interface 527 11.10 Improving the Output 537 11.11 Working with User Input 542 11.12 Forms and Model Forms 546 11.13 More About Views 551 11.14 Look-and-Feel Improvements 553 11.15 Unit Testing 554 11.16 An Intermediate Django App: The TweetApprover 564 11.17 Resources 597 11.18 Conclusion 597 11.19 Exercises 598 Chapter 12: Cloud Computing: Google App Engine 604 12.1 Introduction 605 12.2 What Is Cloud Computing? 605 12.3 The Sandbox and the App Engine SDK 612 12.4 Choosing an App Engine Framework 617 12.5 Python 2.7 Support 626 12.6 Comparisons to Django 628 12.7 Morphing "Hello World" into a Simple Blog 631 12.8 Adding Memcache Service 647 12.9 Static Files 651 12.10 Adding Users Service 652 12.11 Remote API Shell 654 12.12 Lightning Round (with Python Code) 656 12.13 Sending Instant Messages by Using XMPP 660 12.14 Processing Images 662 12.15 Task Queues (Unscheduled Tasks) 663 12.16 Profiling with Appstats 670 12.17 The URLfetch Service 672 12.18 Lightning Round (without Python Code) 673 12.19 Vendor Lock-In 675 12.20 Resources 676 12.21 Conclusion 679 12.22 Exercises 680 Chapter 13: Web Services 684 13.1 Introduction 685 13.2 The Yahoo!
