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