SUMMARY = """
|
|
Python is an interpreted, interactive, object-oriented programming
|
|
language. It is often compared to Tcl, Perl, Scheme or Java.
|
|
|
|
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, as well as to various windowing systems (X11, Motif, Tk,
|
|
Mac, MFC). 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.
|
|
|
|
The Python implementation is portable: it runs on many brands of UNIX,
|
|
on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
|
|
listed here, it may still be supported, if there's a C compiler for
|
|
it. Ask around on comp.lang.python -- or just try compiling Python
|
|
yourself.
