-Introduction
-============
-
-From the `official Python website `_:
-
-Python is a general-purpose, high-level programming language similar
-to Tcl, Perl, Ruby, Scheme, or Java. Some of its main key features
-include:
-
-* very clear, readable syntax
-
- Python's philosophy focuses on readability, from code blocks
- delineated with significant whitespace to intuitive keywords in
- place of inscrutable punctuation
-
-* extensive standard libraries and third party modules for virtually
- any task
-
- Python is sometimes described with the words "batteries included"
- for its extensive
- `standard library `_, which can
- includes modules for regular expressions, file IO, fraction handling,
- object serialization, and much more.
-
- Additionally, the
- `Python Package Index `_ is available
- for users to submit their packages for widespread use, similar to
- Perl's `CPAN `_. There is a thriving community
- of very powerful Python frameworks and tools like
- the `Django `_ web framework and the
- `NumPy `_ set of math routines.
-
-* integration with other systems
-
- Python can integrate with `Java libraries `_,
- enabling it to be used with the rich Java environment that corporate
- programmers are used to. It can also be
- `extended by C or C++ modules `_
- when speed is of the essence.
-
-* ubiquity on computers
-
- Python is available on Windows, \*nix, and Mac. It runs wherever the
- Java virtual machine runs, and the reference implementation CPython
- can help bring Python to wherever there is a working C compiler.
-
-* friendly community
-
- Python has a vibrant and large :ref:`community `
- which maintains wikis, conferences, countless repositories,
- mailing lists, IRC channels, and so much more. Heck, the Python
- community is even helping to write this guide!
