ABOUT Slut is a programming framework for generative, synthetic, interactive, network-enabled graphics. Slut generates images from processes. Such processes may be simple "construction plans" or they may depend on user input. They may be drawn from incoming network data or messages that are sent to the network. Produced images may be adaptive, accumulative or static. They may look and feel like computer games or they may inform like scientific visualizations. They may be lyrical, cynical, political, intrusive (literally over the network), simply beautiful or banal.

The Python Computer Graphics Kit is an Open Source software package containing a collection of Python modules, plugins and utilities that are meant to be useful for any domain where you have to deal with 3D data of any kind, be it for visualization, creating photorealistic images, Virtual Reality or even games.

Provides access to specialized input hardware such as SpaceMouse/SpaceBall, data glove or tablet via wrappers around the 3DxWare SDK by 3Dconnexion, the Wintab Developer Kit by LCS/Telegraphics and the Data Glove SDK by Fifth Dimension Technologies.

The Boost Python Library is a framework for interfacing Python and C++. It allows you to quickly and seamlessly expose C++ classes functions and objects to Python, and vice-versa, using no special tools -- just your C++ compiler. It is designed to wrap C++ interfaces non-intrusively, so that you should not have to change the C++ code at all in order to wrap it, making Boost.Python ideal for exposing 3rd-party libraries to Python. The library's use of advanced metaprogramming techniques simplifies its syntax for users, so that wrapping code takes on the look of a kind of declarative interface definition language (IDL).

PyX is a Python package for the creation of PostScript and PDF files. It combines an abstraction of the PostScript drawing model with a TeX/LaTeX interface. Complex tasks like 2d and 3d plots in publication-ready quality are built out of these primitives.

Pygame only supports Python 2 and not Python 3. However, the programs in this book work with both Python 2 and 3.

Setting Up a Pygame Program

From PyQt4.6, PyQt has two APIs, API#1 (the original), and API#2 (new). API#2 is more Pythonic and eliminates QString and QVariant, and is a bit nicer to use. API#1 remains best for those using PyQt to prototype C++/Qt applications. API#1 is the default for PyQt4.x with Python 2.x, and for PyQt4.0-4.5 with Python 3.x. API#2 is the default for PyQt4.6+ with Python 3.x, and for PySide.

most of the changes affect uses of QDataStream, QSettings, and QTextStream, and of course any use of QString methods (since in API#2, QString is gone, so we use str).

To convert any particular example to PySide the steps are as follows: Replace python3 in the first line with python. Add the following statements before the first import: from __future__ import division from __future__ import print_function from future_builtins import * Replace PyQt4 with PySide throughout (e.g., in the imports) If using Python 2.6 replace {} in format strings with {0}, {1}, etc., as appropriate. Add [0] at the end of every QFileDialog.*() function call. (In PyQt these return a—possibly empty—filename; in PySide they return a filename–filter 2-tuple, but all the examples only need the filename.) Replace QT_VERSION_STR with qVersion(). Replace PYQT_VERSION_STR with PySide.__version__; you will also need to add import PySide in the imports after the future imports. Replace @pyqtSignature with @Slot. Replace def isAlive(qobj): ... with def isAlive(qobj): return True. (There is currently no PySide equivalent.) Replace chr with unichr.

a much better way to write GUI apps in Python is to use Trolltech's QT Designer to WYSIWYG-ly create a nice-looking interface, and then automatically generate the necessary code for it with pyuic (which is a UI compiler for QT that comes with the PyQT package.)

This is PyQt4 tutorial. The tutorial is suited for beginners and intermediate programmers. After reading this tutorial, you will be able to program non trivial PyQt4 applications.

ActiveState research Python for .NET is a near-seamless integration of the CPython runtime with the .NET Common Language Runtime (CLR). IronPython is an implementation of Python for .net, which allows you to import .net class libraries seamlessly in Python.

it is advised to somehow mix together (e.g. using exclusive or) the hash values for the components of the object that also play a part in comparison of objects.

If a class does not define a __cmp__() or __eq__() method it should not define a __hash__() operation either

Called when an attribute lookup has not found the attribute in the usual places (i.e. it is not an instance attribute nor is it found in the class tree for self). name is the attribute name. This method should return the (computed) attribute value or raise an AttributeError exception.

class foo: def __init__(self, n): self.n = n def __call__(self, i): self.n += i return self.n

function foo (n) { return function (i) { return n += i } }
