...Python class definition. There are three cooperating parts to the proposed mechanism: the use of the last slot in the type object structure to store a pointer to a rich comparison function the addition of special methods for classes the addition of an optional argument to the builtin cmp() function. Motivation The current comparison protocol for Python objects assumes that any two Python objects can be compared (as of Python 1.5, object comparisons can raise exceptions), and that the return ...
...interpreter, or of Python applications. This release includes just a small number of fixes, primarily preventing crashes of the interpreter in certain boundary cases. Python 2.5 is the latest release of Python. This release of the older 2.4 code is to provide bug fixes for people who are still using Python 2.4. This is the last planned release in the Python 2.4 series - future maintenance releases of Python will be in the 2.5 series, starting of course with 2.5.1. We have decided not to include ...
Released: March 11, 2008
Python 2.4 is now in security-fix-only mode. No new features are being added, and bugs are not fixed anymore unless they affect the stability and security of the interpreter, or of Python …

...Python functions. The new name resolution semantics will take effect with Python 2.2. These semantics will also be available in Python 2.1 by adding "from __future__ import nested_scopes" to the top of a module. (See PEP 236.) The Python 2.0 definition specifies exactly three namespaces to check for each name -- the local namespace, the global namespace, and the builtin namespace. According to this definition, if a function A is defined within a function B, the names bound in B are not visib...
...Python 2.0 and 2.1, files were interpreted as Latin-1 for a transitional period. This transition ended with Python 2.5, which gives an error if non-ASCII characters are encountered and no source encoding is declared. Rationale With PEP 263, using arbitrary non-ASCII characters in a Python file is possible, but tedious. One has to explicitly add an encoding declaration. Even though some editors (like IDLE and Emacs) support the declarations of PEP 263, many editors still do not (and never will)...

...interpreter simpler and faster. By implementing new features as AST transformations, the existing compiler can generate the bytecode for a feature without having to modify the interpreter. A stable interpreter is necessary if we are to improve the performance and portability of the CPython VM. Rationale Python is both expressive and easy to learn; it is widely recognized as the easiest-to-learn, widely used programming language. However, it is not the most flexible. That title belongs to lisp...

...Python and Jython, the Java implementation of Python, were chosen because they would allow both the PowerPC and Java implementations of the PanMachine to execute the same user interface layouts. Python, implemented in C, was used on the PowerPC, and Jython, implemented in Java, was used in the browser applet. Implementation in Python Re-implementation using Python went smoothly. The Python language interpreter and support libraries are written in C and can be compiled with most C compilers. I...
...Python-scripted HTML. Some of the modules, such as the search spider, GUI, and HTTP server, were written in Python. For performance reasons, others, such as the query engine, indexer, and HTML parser, use the Python/C API to incorporate functionality written in C. The C-based search engine core was also wrapped as a Python extension module. Some C++ is used in the interfaces to key third party technologies. Python's flexibility in this regard gave us a wide degree of flexibility in integration. ...
...Python. This is done because we want files with a foreign newline convention to be import-able, so a Python Lib directory can be shared over a remote file system connection, or between MacPython and Unix-Python on Mac OS X. For this to be feasible the universal newline convention needs to have a reasonably small impact on performance, which means a Python implementation is not an option as it would bog down all imports. And because of files with multiple newline conventions, which Visual C++ an...
...Python-C API, so I expected at most modest speed up compared to f7(). Given the effort of writing and testing an extension (compared to whipping up those Python one-liners), as well as the dependency on a non-standard Python extension, I decided not to pursue this option... Conclusion If you feel the need for speed, go for built-in functions - you can't beat a loop written in C. Check the library manual for a built-in function that does what you want. If there isn't one, h...
