Python is an easy to learn, powerful programming language. It has efficient
|
|
|
|
high-level data structures and a simple but effective approach to
|
|
|
|
object-oriented programming. Python's elegant syntax and dynamic typing,
|
|
|
|
together with its interpreted nature, make it an ideal language for scripting
|
|
|
|
and rapid application development in many areas on most platforms.
|
|
|
|
|
|
|
|
The Python interpreter and the extensive standard library are freely available
|
2021-07-26 19:11:55 -03:00
|
|
|
in source or binary form for all major platforms from the Python web site,
|
2014-10-29 04:36:35 -03:00
|
|
|
https://www.python.org/, and may be freely distributed. The same site also
|
2007-08-15 11:28:22 -03:00
|
|
|
contains distributions of and pointers to many free third party Python modules,
|
|
|
|
programs and tools, and additional documentation.
|
|
|
|
|
|
|
|
The Python interpreter is easily extended with new functions and data types
|
|
|
|
implemented in C or C++ (or other languages callable from C). Python is also
|
|
|
|
suitable as an extension language for customizable applications.
|
|
|
|
|
|
|
|
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 all examples are self-contained,
|
|
|
|
so the tutorial can be read off-line as well.

For a description of standard objects and modules, see :ref:`library-index`.
|
|
|
|
:ref:`reference-index` gives a more formal definition of the language. To write
|
|
|
|
extensions in C or C++, read :ref:`extending-index` and
|
|
|
|
:ref:`c-api-index`. There are also several books covering Python in depth.
