Reviews Author: Mark Lutz Pub Date: 2014 ISBN: 978-0-596-15810-1 Pages: 1628 Language: English Format: PDF Size: 24 Mb 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 Python’s 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.

PyEdit Changes in Version 2.1 (Fourth Edition) Besides the updates described in the prior section, the following additional enhancements were made for this current fourth edition of this book: • PyEdit has been ported to run under Python 3.1, and its tkinter library. • The nonmodal change and font dialogs were fixed to work better if multiple instance windows are open: they now use per-dialog state. • A Quit request in main windows now verifies program exit if any other edit windows in the process have changed content, instead of exiting silently.

• There’s a new Grep menu option and dialog for searching external files; searches are run in threads to avoid blocking the GUI and to allow multiple searches to overlap in time and support Unicode text. • There was a minor fix for initial positioning when text is inserted initially into a newly created editor, reflecting a change in underlying libraries.

• The Run Code option for files now uses the base file name instead of the full directory path after a chdirto better support relative paths; allows for command-line arguments to code run from files; and inherits a patch made in Chapter 5’s launchmodeswhich converts /to in script paths. In addition, this option always now runs an updatebetween pop-up dialogs to ensure proper display.

• Perhaps most prominently, PyEdit now processes files in such a way as to support display and editing of text with arbitrary Unicode encodings, to the extent allowed by the underlying Tk GUI library for Unicode strings. Specifically, Unicode is taken into account when opening and saving files; when displaying text in the GUI; and when searching files in directories.

The following sections provide additional implementation notes on these changes. Html2text: Extracting Text from HTML (Prototype, Preview) Example 14-8lists the code of the simple-minded HTML parser that PyMailGUI uses to extract plain text from mails whose main (or only) text part is in HTML form. This extracted text is used both for display and for the initial text in replies and forwards.

Its original HTML form is also displayed in its full glory in a popped-up web browser as before. This is a prototype. Zuma Blitz Popcap Games there. Because PyMailGUI is oriented toward plain text today, this parser is intended as a temporary workaround until a HTML viewer/editor widget solution is found.
