1822 Python is an interpreted, interactive, object-oriented programming
1823 language. It is often compared to Tcl, Perl, Scheme or Java.
1825 Python combines remarkable power with very clear syntax. It has
1826 modules, classes, exceptions, very high level dynamic data types, and
1827 dynamic typing. There are interfaces to many system calls and
1828 libraries, as well as to various windowing systems (X11, Motif, Tk,
1829 Mac, MFC). New built-in modules are easily written in C or C++. Python
1830 is also usable as an extension language for applications that need a
1831 programmable interface.
1833 The Python implementation is portable: it runs on many brands of UNIX,
1834 on Windows, DOS, OS/2, Mac, Amiga... If your favorite system isn't
1835 listed here, it may still be supported, if there's a C compiler for
1836 it. Ask around on comp.lang.python -- or just try compiling Python
