  • Foreword for "Programming Python" (2nd ed.)

    ...output. Personally, it's the Python 2.0 feature I use most frequently, but most people who opened their mouth about found it an abomination. The discussion thread on the newsgroup berating this simple language extension was one of the longest ever -- apart from the never-ending Python vs. Perl thread. Which brings me to the next topic. (No, not Python vs. Perl. There are better places to pick a fight than a foreword.) I mean the speed of Python's evolution, a topic dear to the hear...

    ...output OK: Python-3.11.0.tgz, which indicates that the signature is valid. Migrating from GPG signatures Before Sigstore signatures were available, CPython also provided GPG signatures as a means of verifying the origin and integrity of artifacts. Below are some tips for migrating an existing configuration verifying using GPG to adopting Sigstore. Instead of using a GPG key for verification, use the above table to choose which signing identity and OIDC issuer is expected for each Python release ...

New features include a <BLANKLINE> marker for expected output containing blank lines, options to produce unified or context diffs when actual output doesn't match expectations, an option to normalize whitespace before comparing, and an option to use an ellipsis to signify "don't care" regions of output. Tkinter now supports the wish -sync and -use options. The following methods in time support passing of None: ctime(), gmtime(), and localtime(). If None is provided, ...

    ...output was based on the raw scoring data. The aggregation engine was added once the system was scaled up to 800 cities, increasing the data stream by almost 4000%. In the first half of 2004, the system has already scored over 4 million forecasts, all collected, parsed, and displayed on the web. ForecastWatch.com can be used to determine the accuracy of weather forecasts, for example by reviewing maps of error magnitude in forecast low and high temperatures Zoom in The last component in Forec...

Many small improvements to the quality of the documentation, both PostScript, HTML and even Emacs info (library manual only). New module telnetlib.py. New tool versioncheck. Two bugs with ftp URLs fixed in urllib.py. Fixed infinite recursion when printing __builtins__. A bunch of small problems fixed in Tkint...

    ...output is sent by the HTTP server to the user's browser. Although this was a fairly simple exercise, we did run into some problems stemming from our design of the CORE database meta-class. We found that altering classes and modules at runtime, as is done by the meta-class, violates guidelines imposed by Python's optional restricted execution environment. Since we felt that restricted execution was a necessary component in supporting a persistent web module, we opted to deploy CORE using CGIs rat...

    ...output is easy to parse into the desired results. However, these programs don't always work correctly, are not fully documented, and it's often hard to determine all the possible failure cases from the outside. To compensate for this, the PyDrone developers wrote tests to anticipate as many error cases as possible, but it was impossible to rule out additional unexpected error cases after deployment. From experience dealing with this issue first in Perl (Drone) and then in Python (PyDrone), we fo...

This is quite un-doctest-like, but is practical. The behavior can be disabled by passing the new doctest module constant DONT_ACCEPT_TRUE_FOR_1 to the new optionflags optional argument.
