Python is a simple, yet powerful programming language that bridges the gap between C and shell programming, and is thus ideally suited for ``throw-away programming'' and rapid prototyping. Its syntax is put together from constructs borrowed from a variety of other languages; most prominent are influences from ABC, C, Modula-3 and Icon.
The Python interpreter is easily extended with new functions and data types implemented in C. Python is also suitable as an extension language for highly customizable C applications such as editors or window managers.
Python is available for various operating systems, amongst which several flavors of Unix, the Apple Macintosh, MS-DOS, Windows (3.1(1), '95 and NT flavors), OS/2, and others.
This tutorial introduces the reader informally to the basic concepts and features of the Python language and system. It helps to have a Python interpreter handy for hands-on experience, but as the examples are self-contained, the tutorial can be read off-line as well.
For a description of standard objects and modules, see the Python Library Reference document. The Python Reference Manual gives a more formal definition of the language.
