| 82 | <H3>Abstract:</H3> |
| 83 | <DIV CLASS="ABSTRACT"> |
| 84 | |
| 85 | <P> |
| 86 | Python is an easy to learn, powerful programming language. It has |
| 87 | efficient high-level data structures and a simple but effective |
| 88 | approach to object-oriented programming. Python's elegant syntax and |
| 89 | dynamic typing, together with its interpreted nature, make it an ideal |
| 90 | language for scripting and rapid application development in many areas |
| 91 | on most platforms. |
| 92 | |
| 93 | <P> |
| 94 | The Python interpreter and the extensive standard library are freely |
| 95 | available in source or binary form for all major platforms from the |
| 96 | Python Web site, <a class="url" href="http://www.python.org/">http://www.python.org/</a>, and may be freely |
| 97 | distributed. The same site also contains distributions of and |
| 98 | pointers to many free third party Python modules, programs and tools, |
| 99 | and additional documentation. |
| 100 | |
| 101 | <P> |
| 102 | The Python interpreter is easily extended with new functions and data |
| 103 | types implemented in C or C++ (or other languages callable from C). |
| 104 | Python is also suitable as an extension language for customizable |
| 105 | applications. |
| 106 | |
| 107 | <P> |
| 108 | This tutorial introduces the reader informally to the basic concepts |
| 109 | and features of the Python language and system. It helps to have a |
| 110 | Python interpreter handy for hands-on experience, but all examples are |
| 111 | self-contained, so the tutorial can be read off-line as well. |
| 112 | |
| 113 | <P> |
| 114 | For a description of standard objects and modules, see the |
| 115 | <em class="citetitle"><a |
| 116 | href="../lib/lib.html" |
| 117 | title="Python Library Reference" |
| 118 | >Python Library Reference</a></em> document. The |
| 119 | <em class="citetitle"><a |
| 120 | href="../ref/ref.html" |
| 121 | title="Python Reference Manual" |
| 122 | >Python Reference Manual</a></em> gives a more |
| 123 | formal definition of the language. To write extensions in C or |
| 124 | C++, read <em class="citetitle"><a |
| 125 | href="../ext/ext.html" |
| 126 | title="Extending and Embedding the |
| 127 | Python Interpreter" |
| 128 | >Extending and Embedding the |
| 129 | Python Interpreter</a></em> and <em class="citetitle"><a |
| 130 | href="../api/api.html" |
| 131 | title="Python/C API |
| 132 | Reference" |
| 133 | >Python/C API |
| 134 | Reference</a></em>. There are also several books covering Python in depth. |
| 135 | |
| 136 | <P> |
| 137 | This tutorial does not attempt to be comprehensive and cover every |
| 138 | single feature, or even every commonly used feature. Instead, it |
| 139 | introduces many of Python's most noteworthy features, and will give |
| 140 | you a good idea of the language's flavor and style. After reading it, |
| 141 | you will be able to read and write Python modules and programs, and |
| 142 | you will be ready to learn more about the various Python library |
| 143 | modules described in the <em class="citetitle"><a |
| 144 | href="../lib/lib.html" |
| 145 | title="Python Library |
| 146 | Reference" |
| 147 | >Python Library |
| 148 | Reference</a></em>. |
