1821 SUMMARY = """ |
|
1822 Python is an interpreted, interactive, object-oriented programming |
|
1823 language. It is often compared to Tcl, Perl, Scheme or Java. |
|
1824 |
|
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. |
|
1832 |
|
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 |
|
1837 yourself. |
