- Clarified and expanded explanation of implied slice indices in Example 3.9, “スライシングの略記”. Thanks Petr.
- Added historical note in Section 5.5, “Exploring UserDict: A Wrapper Class” now that Python 2.2 supports subclassing built-in datatypes directly.
- Added explanation of update dictionary method in Example 5.9, “Defining the UserDict Class”. Thanks Petr.
- Clarified Python's lack of overloading in Section 5.5, “Exploring UserDict: A Wrapper Class”. Thanks Petr.
- Fixed typo in Example 8.8, “Introducing BaseHTMLProcessor”. HTML comments end with two dashes and a bracket, not one. Thanks Petr.
- Changed tense of note about nested scopes in Section 8.5, “locals and globals” now that Python 2.2 is out. Thanks Petr.
- Fixed typo in Example 8.14, “Dictionary-based string formatting in BaseHTMLProcessor.py”; a space should have been a non-breaking space. Thanks Petr.
- Added title to note on derived classes in Section 5.5, “Exploring UserDict: A Wrapper Class”. Thanks Petr.
- Added title to note on downloading unittest in Section 15.3, “Refactoring”. Thanks Petr.
- Fixed typesetting problem in Example 16.6, “Running scripts in the current directory”; tabs should have been spaces, and the line numbers were misaligned. Thanks Petr.
- Fixed capitalization typo in the tip on truth values in Section 3.2, “リストの紹介”. It's True and False, not true and false. Thanks to everyone who pointed this out.
- Changed section titles of Section 3.1, “辞書の紹介”, Section 3.2, “リストの紹介”, and Section 3.3, “タプルの紹介”. "Dictionaries 101" was a cute way of saying that this section was an beginner's introduction to dictionaries. American
colleges tend to use this numbering scheme to indicate introductory courses with no prerequisites, but apparently this is
a distinctly American tradition, and it was unnecessarily confusing my international readers. In my defense, when I initially
wrote these sections a year and a half ago, it never occurred to me that I would have international readers.
- Upgraded to version 1.52 of the DocBook XSL stylesheets.
- Upgraded to version 6.52 of the SAXON XSLT processor from Michael Kay.

- Added note in Section 5.5, “Exploring UserDict: A Wrapper Class” about derived classes always overriding ancestor classes.
- Fixed typo in Example 5.18, “Modifying Class Attributes”. Thanks to Kevin for the correction.
- Added note in Section 6.1, “Handling Exceptions” that you can define and raise your own exceptions. Thanks to Rony for the suggestion.
- Fixed typo in Example 8.17, “Handling specific tags”. Thanks for Rick for the correction.

- Added Section 10.1, “Abstracting input sources”.
- Added Section 10.2, “Standard input, output, and error”.
- Added simple counter for loop examples (good usage and bad usage) in Section 6.3, “Iterating with for Loops”. Thanks to Kevin for the idea.
- Fixed typo in Example 3.25, “keys 関数, values 関数, items 関数” (two elements of params.values() were reversed).
- Fixed mistake in Section 4.3, “type, str, dir や他の組み込み関数を使う” with regards to the name of the __builtin__ module. Thanks to Denis for the correction.
- Added additional example in Section 16.2, “Finding the path” to show how to run unit tests in the current working directory, instead of the directory where regression.py is located.
- Modified explanation of how to derive a negative list index from a positive list index in Example 3.7, “リストの負のインデックス”. Thanks to Renauld for the suggestion.
- Updated links on home page for downloading latest version of Python.
- Added link on home page to Bruce Eckel's preliminary draft of Thinking in Python, a marvelous (and advanced) book on design patterns and how to implement them in Python.
2001-11-18 (3.8)
2001-09-30 (3.7)
- Added Section 9.2, “Packages”.
- Added Section 9.3, “Parsing XML”.
- Cleaned up introductory paragraph in Section 9.1, “Diving in”. Thanks to Matt for this suggestion.
- Added Java tip in Section 5.2, “from module import を使ってのインポート”. Thanks to Ori for this suggestion.
- Fixed mistake in Section 4.8, “全てをまとめる” where I implied that you could not use is None to compare to a null value in Python. In fact, you can, and it's faster than == None. Thanks to Ori pointing this out.
- Clarified in Section 3.2, “リストの紹介” where I said that li = li + other was equivalent to li.extend(other). The result is the same, but extend is faster because it doesn't create a new list. Thanks to Denis pointing this out.
- Fixed mistake in Section 3.2, “リストの紹介” where I said that li += other was equivalent to li = li + other. In fact, it's equivalent to li.extend(other), since it doesn't create a new list. Thanks to Denis pointing this out.
- Fixed typographical laziness in Chapter 2, 初めての Python プログラム; when I was writing it, I had not yet standardized on putting string literals in single quotes within the text. They were
set off by typography, but this is lost in some renditions of the book (like plain text), making it difficult to read. Thanks
to Denis for this suggestion.
- Fixed mistake in Section 2.2, “関数の宣言” where I said that statically typed languages always use explicit variable + datatype declarations to enforce static typing.
Most do, but there are some statically typed languages where the compiler figures out what type the variable is based on
usage within the code. Thanks to Tony for pointing this out.
- Added link to Spanish translation.
2001-09-06 (3.6.4)
2001-09-04 (3.6.3)

- Fixed long-standing bug in colorizing script that improperly colorized the examples in Chapter 8, HTML Processing.
- Added link to French translation. They did the right thing and translated the source XML, so they can re-use all my build scripts and make their work available in six different formats.
- Upgraded to version 1.43 of the DocBook XSL stylesheets.
- Upgraded to version 6.43 of the SAXON XSLT processor from Michael Kay.
- Massive stylesheet changes, moving away from a table-based layout and towards more appropriate use of cascading style sheets.
Unfortunately, CSS has as many compatibility problems as anything else, so there are still some tables used in the header and footer. The resulting
HTML version looks worse in Netscape 4, but better in modern browsers, including Netscape 6, Mozilla, Internet Explorer 5, Opera 5, Konqueror, and iCab. And it's still completely readable in Lynx. I love Lynx. It was my first web browser. You never forget your first.
- Moved to Ant to have better control over the build process, which is especially important now that I'm juggling six output formats and
two languages.
- Consolidated the available downloadable archives; previously, I had different files for each platform, because the .zip files
that Python's zipfile module creates are non-standard and can't be opened by Aladdin Expander on Mac OS. But the .zip files that Ant creates are completely standard and cross-platform. Go Ant!
- Now hosting the complete XML source, XSL stylesheets, and associated scripts and libraries on SourceForge. There's also CVS access for the really adventurous.
- Re-licensed the example code under the new-and-improved GPL-compatible Python 2.1.1 license. Thanks, Guido; people really do care, and it really does matter.

- The Word version is now in native Word format, compatible with Word 97.
- The PDF and text versions now have fewer problems with improperly converted special characters (like trademark symbols and curly
quotes).
- Added link to download Word version for UNIX, in case some twisted soul wants to import it into StarOffice or something.
- Fixed several notes which were missing titles.
- Fixed stylesheets to work around bug in Internet Explorer 5 for Mac OS which caused colorized words in the examples to be displayed in the wrong font. (Hello?!? Microsoft? Which part of <pre> don't you understand?)
- Fixed archive corruption in Mac OS downloads.
- In first section of each chapter, added link to download examples. (My access logs show that people skim or skip the two
pages where they could have downloaded them (the home page and preface), then scramble to find a download link once they actually start reading.)
- Tightened the home page and preface even more, in the hopes that someday someone will read them.
- Soon I hope to get back to actually writing this book instead of debugging it.

- Fixed important error in Section 2.2, “関数の宣言”: functions that do not explicitly return a value return None, so you can assign the return value of such a function to a variable without raising an exception.
- Added minor clarifications to Section 2.3, “関数の文書化”, Section 2.4, “全てはオブジェクト”, and Section 3.4, “変数の宣言”.
2001-02-02 (2.2)
