1466Python is an interpreted, interactive, object-oriented programming
1467language. It is often compared to Tcl, Perl, Scheme or Java.
1468
1469Python combines remarkable power with very clear syntax. It has
1470modules, classes, exceptions, very high level dynamic data types, and
1471dynamic typing. There are interfaces to many system calls and
1472libraries, as well as to various windowing systems (X11, Motif, Tk,
1473Mac, MFC). New built-in modules are easily written in C or C++. Python
1474is also usable as an extension language for applications that need a
1475programmable interface.
1476
1477The Python implementation is portable: it runs on many brands of UNIX,
1478on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
1479listed here, it may still be supported, if there's a C compiler for
1480it. Ask around on comp.lang.python -- or just try compiling Python
1481yourself.
