optparse_gui is a drop-in replacement for Python's built-in optparse. It allows the user to enter command line arguments in a dynamically generated WX-based dialog. optparse_gui generates the dialog depending on the provided optparse options: CheckBox for boolean options, ComboBox for "choice" options, TextCtrl for all other options, and an extra TextCtrl for entering non-option command line arguments. Also, the dialog contains context-sensitive help for every option.
python-money provides carefully designed basic Python primitives for working with money and currencies. The primary objectives of this module is to aid in the development of financial applications by increasing testability and reusability, reducing code duplication and reducing the risk of defects occurring in the code. The module defines two basic Python classes: a Currency class and a Money class. It also pre-defines all the world's currencies, according to the ISO 4217 standard.
tinypy is a minimalist implementation of Python in 64k of code. It includes a parser and bytecode compiler written in python. tinypy runs on its own C-based virtual machine with garbage collection. It supports a fairly decent subset of Python, including classes with single inheritance, functions with variable or keyword arguments, strings, lists, dicts, numbers, modules, list comprehensions, exceptions with full traceback, some builtins, and several modules.
txOpenID is an implementation of the OpenID Identity Provider specification, written using Twisted Web and Divmod's Nevow. It reads authentication data and user Web sessions out of a MySQL database using MySQLdb and Twisted Enterprise's adbapi layer. txOpenID currently supports version 1.1 of the OpenID specification.
simplejson is a simple, fast, complete, correct, and extensible JSON encoder and decoder for Python 2.3+. It is pure Python code with no dependencies, but includes an optional C extension for a serious speed boost. The encoder may be subclassed to provide serialization in any kind of situation, without any special support by the objects to be serialized (somewhat like pickle). The decoder can handle incoming JSON strings of any specified encoding (UTF-8 by default).
