• What's New In Python 3.0

  ...by pychecker. Issue #3650: Fixed a reference leak in bytes.split('x'). bytes(o) now tries to use o.__bytes__() before using fallbacks. Issue #1204: The configure script now tests for additional libraries that may be required when linking against readline. This fixes issues with x86_64 builds on some platforms (a few Linux flavors and OpenBSD). C API PyObject_Bytes and PyBytes_FromObject were added. Library Issue #3756: make re.escape() handle bytes as well as str. Issue #3800: fix filte...

  ...object oriented language, its suitability for rapid prototyping, and its extensive standard libraries made it ideal for a project with rapidly changing requirements. Hardware of the CD/DVD Disc Partitioner The CD/DVD disc partitioner, designed by Micro Image Precision Co, is composed of six disc counting and picking machines. Each of these can pick up a fixed number of disks from an input spindle, move the disks forward, and release them on an empty spindle. The six spindles are moved among th...

• Python Success Stories

  ...by allowing the patching of modules, classes, methods or attributes with arbitrary objects at runtime. This allows tests to easily eliminate dependencies of the code under test, and thus concentrating on testing one thing at at time. Additionally, it makes it easy to stimulate particular behaviours or failure modes during the test. For example, by patching the file 'open' function with another function which simply raises an exception, a test can easily verify how the code under test reacts if i...

• Built-in Package Support in Python 1.5

  ...by giving their full name. For example, the Sound package used in the example could be installed in the directory $prefix/lib/python1.5/site-packages/Sound to enable imports statements like import Sound.Effects.echo). Adding a Level of Indirection Some sites wish to install their packages in other places, but still wish them to to be importable by all Python programs run by all their users. This can be accomplished by two different means: Symbolic Links If the package ...

• PSF Trademark Frequently Asked Questions (FAQ)

  ...By analogy, suppose Tim Parkin (creator of the Python logo, and assigner of its copyright and trademark to the PSF) were to print out the Python logo, and sign, number, and date that print. Possibly someone would pay money for the prestige of having a distinct and unique physical object that utilizes the Python logo. If he were to do this, Tim's signature might add value to this one-of-a-kind (because signed) item, but it would not affect his assignment of IP rights to the PSF. An NFT is essenti...

• Computer Programming for Everybody

  ...by identifying the relationships between static program components. One example of this kind of analysis tool is Womble, which extracts object models from Java bytecodes [Jackson]. Womble extracts object model directly from source (or object) code, rather than from a formal specification. Because this method does not rely on the existence of a formal specification (such as a UML model), we believe it is more accessible to ordinary users. A similar approach can be used for analyzing Python ...
