- New library module difflib.py, primarily packaging the SequenceMatcher
class at the heart of the popular ndiff.py file-comparison tool.
- doctest.py (a framework for verifying Python code examples in docstrings)
is now part of the std library.
Windows changes
- Build: Subproject _test (effectively) renamed to _testcapi.
- Import is now case-sensitive. PEP 235 (Import on Case-Insensitive
Platforms) is implemented. See
http://python.sourceforge.net/peps/pep-0235.html
for full details, especially the "Current Lower-Left Semantics" section.
The new Windows import rules are simpler than before:
A. If the PYTHONCASEOK environment variable exists, same as
before: silently accept the first case-insensitive match of any
kind; raise ImportError if none found.
B. Else search sys.path for the first case-sensitive match; raise
ImportError if none found.
The same rules have been implented on other platforms with case-
insensitive but case-preserving filesystems too (including Cygwin, and
several flavors of Macintosh operating systems).
- winsound module: Under Win9x, winsound.Beep() now attempts to simulate
what it's supposed to do (and does do under NT and 2000) via direct
port manipulation. It's unknown whether this will work on all systems,
but it does work on my Win98SE system now and was known to be useless on
