1764	n/a	Python is an interpreted, interactive, object-oriented programming
1765	n/a	language. It is often compared to Tcl, Perl, Scheme or Java.
1766	n/a
1767	n/a	Python combines remarkable power with very clear syntax. It has
1768	n/a	modules, classes, exceptions, very high level dynamic data types, and
1769	n/a	dynamic typing. There are interfaces to many system calls and
1770	n/a	libraries, as well as to various windowing systems (X11, Motif, Tk,
1771	n/a	Mac, MFC). New built-in modules are easily written in C or C++. Python
1772	n/a	is also usable as an extension language for applications that need a
1773	n/a	programmable interface.
1774	n/a
1775	n/a	The Python implementation is portable: it runs on many brands of UNIX,
1776	n/a	on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
1777	n/a	listed here, it may still be supported, if there's a C compiler for
1778	n/a	it. Ask around on comp.lang.python -- or just try compiling Python
