 524  <h2>Python</h2>
 525
 526  Python is an interpreted, interactive, object-oriented programming
 527  language often compared to Tcl, Perl, Scheme, or Java.
 528
 529  <p> Python combines remarkable power with very clear syntax. It has
 530  modules, classes, exceptions, very high level dynamic data types, and
 531  dynamic typing.  There are interfaces to many system calls and
 532  libraries, and new built-in modules are easily written in C or
 533  C++. Python is also usable as an extension language for applications
 534  that need a programmable interface.  <p>
 535
 536  <h2>wxWindows</h2>
 537
 538  wxWindows is a free C++ framework designed to make cross-platform
 539  programming child's play. Well, almost. wxWindows 2 supports Windows
 540  3.1/95/98/NT, Unix with GTK/Motif/Lesstif, with a Mac version
 541  underway. Other ports are under consideration.  <p>
 542
 543  wxWindows is a set of libraries that allows C++ applications to
 544  compile and run on several different types of computers, with minimal
 545  source code changes.  There is one library per supported GUI (such as
 546  Motif, or Windows). As well as providing a common API (Application
 547  Programming Interface) for GUI functionality, it provides
 548  functionality for accessing some commonly-used operating system
 549  facilities, such as copying or deleting files. wxWindows is a
 550  'framework' in the sense that it provides a lot of built-in
 551  functionality, which the application can use or replace as required,
 552  thus saving a great deal of coding effort. Basic data structures such
 553  as strings, linked lists and hash tables are also supported.
 554
 555  <p>
 556  <h2>wxPython</h2>
 557
 558  wxPython is a Python extension module that encapsulates the wxWindows
 559  GUI classes. Currently it is only available for the Win32 and GTK
 560  ports of wxWindows, but as soon as the other ports are brought up to
 561  the same level as Win32 and GTK, it should be fairly trivial to
 562  enable wxPython to be used with the new GUI.
 563
 564  <p>
 565
 566  The wxPython extension module attempts to mirror the class heiarchy
 567  of wxWindows as closely as possible. This means that there is a
 568  wxFrame class in wxPython that looks, smells, tastes and acts almost
 569  the same as the wxFrame class in the C++ version. Unfortunately,
 570  because of differences in the languages, wxPython doesn't match
 571  wxWindows exactly, but the differences should be easy to absorb
 572  because they are natural to Python. For example, some methods that
 573  return multiple values via argument pointers in C++ will return a
 574  tuple of values in Python.
 575
 576  <p>
 577
 578  There is still much to be done for wxPython, many classes still need
 579  to be mirrored. Also, wxWindows is still somewhat of a moving target
 580  so it is a bit of an effort just keeping wxPython up to date. On the
 581  other hand, there are enough of the core classes completed that
 582  useful applications can be written.
 583
 584  <p>
 585
 586  wxPython is close enough to the C++ version that the majority of
 587  the wxPython documentation is actually just notes attached to the C++
 588  documents that describe the places where wxPython is different. There
 589  is also a series of sample programs included, and a series of
 590  documentation pages that assist the programmer in getting started
 591  with wxPython.
