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, 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. | |
