<h2>Python</h2>
Python is an interpreted, interactive, object-oriented programming
language often compared to Tcl, Perl, Scheme, or Java.
<p> Python combines remarkable power with very clear syntax. It has
modules, classes, exceptions, very high level dynamic data types, and
dynamic typing. There are interfaces to many system calls and
libraries, and new built-in modules are easily written in C or
C++. Python is also usable as an extension language for applications
that need a programmable interface. <p>
<h2>wxWindows</h2>
wxWindows is a free C++ framework designed to make cross-platform
programming child's play. Well, almost. wxWindows 2 supports Windows
3.1/95/98/NT, Unix with GTK/Motif/Lesstif, with a Mac version
underway. Other ports are under consideration. <p>
wxWindows is a set of libraries that allows C++ applications to
compile and run on several different types of computers, with minimal
source code changes. There is one library per supported GUI (such as
Motif, or Windows). As well as providing a common API (Application
Programming Interface) for GUI functionality, it provides
functionality for accessing some commonly-used operating system
facilities, such as copying or deleting files. wxWindows is a
'framework' in the sense that it provides a lot of built-in
functionality, which the application can use or replace as required,
thus saving a great deal of coding effort. Basic data structures such
as strings, linked lists and hash tables are also supported.
<p>
<h2>wxPython</h2>
wxPython is a Python extension module that encapsulates the wxWindows
GUI classes. Currently it is only available for the Win32 and GTK
ports of wxWindows, but as soon as the other ports are brought up to
the same level as Win32 and GTK, it should be fairly trivial to
enable wxPython to be used with the new GUI.
<p>
The wxPython extension module attempts to mirror the class heiarchy
of wxWindows as closely as possible. This means that there is a
wxFrame class in wxPython that looks, smells, tastes and acts almost
the same as the wxFrame class in the C++ version. Unfortunately,
because of differences in the languages, wxPython doesn't match
wxWindows exactly, but the differences should be easy to absorb
because they are natural to Python. For example, some methods that
return multiple values via argument pointers in C++ will return a
tuple of values in Python.
<p>
There is still much to be done for wxPython, many classes still need
to be mirrored. Also, wxWindows is still somewhat of a moving target
so it is a bit of an effort just keeping wxPython up to date. On the
other hand, there are enough of the core classes completed that
useful applications can be written.
<p>
wxPython is close enough to the C++ version that the majority of
the wxPython documentation is actually just notes attached to the C++
documents that describe the places where wxPython is different. There
is also a series of sample programs included, and a series of
documentation pages that assist the programmer in getting started
with wxPython.
