1579Python is an interpreted, interactive, object-oriented programming
1580language. It is often compared to Tcl, Perl, Scheme or Java.
1581
1582Python combines remarkable power with very clear syntax. It has
1583modules, classes, exceptions, very high level dynamic data types, and
1584dynamic typing. There are interfaces to many system calls and
1585libraries, as well as to various windowing systems (X11, Motif, Tk,
1586Mac, MFC). New built-in modules are easily written in C or C++. Python
1587is also usable as an extension language for applications that need a
1588programmable interface.
1589
1590The Python implementation is portable: it runs on many brands of UNIX,
1591on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
1592listed here, it may still be supported, if there's a C compiler for
1593it. Ask around on comp.lang.python -- or just try compiling Python
1594yourself.
