This page covers the information how to include a Python snippets into your LaTeX presenation

====== Listings ======


Listings LaTeX package can highlight source code written in many languages including LaTeX. 

A minimal Python example is:

<code latex>
\documentclass{article}
\usepackage[procnames]{listings}
\usepackage{color}

\begin{document}
\definecolor{keywords}{RGB}{255,0,90}
\definecolor{comments}{RGB}{0,0,113}
\definecolor{red}{RGB}{160,0,0}
\definecolor{green}{RGB}{0,150,0}

\lstset{language=Python, 
        basicstyle=\ttfamily\small, 
        keywordstyle=\color{keywords},
        commentstyle=\color{comments},
        stringstyle=\color{red},
        showstringspaces=false,
        identifierstyle=\color{green},
        procnamekeys={def,class}}

\begin{lstlisting}
def hello(name):
    print 'Hello', name

if __name__=='__main__':
    hello('Me')    
\end{lstlisting}

\end{document}

</code>

The source code can be also available in separate Python files and then included in the document with latex command <code>\lstinputlisting{example.py}</code> (which allows you the modify and test the code easily.

LaTeX files can be also generated automatically from Python scripts ([[http://gael-varoquaux.info/computers/pyreport/|pyreport]]) or from wiki ([[http://www-user.tu-chemnitz.de/~mren/wiki2beamer/doku.php|wiki2beamer]])

====== Pygments ======

If you need more detailed highlighting of Python syntax you can use [[http://pygments.org/|Pygments]].
