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