LaTeX技巧473：Listings宏包定制python源代码输出

listing使用方法前面博文已经写了很多了有：LaTeX技巧32：LaTeX程序代码排版，Listings宏包以及 LaTex技巧35：listings的范例程序还有制作 matlab样式的代码如：LaTeX技巧57：使用mcode宏包在LATEX制作m文件效果LaTeX技巧466：如何利用listing宏包制作专业的C++输出代码？ LaTeX技巧450：Latex中插入彩色java代码

下面我们看看python代码如何制作呢？
我们给出了一个语法文件（选自这里） 其效果图如下：

代码如下：

\documentclass{article}
\usepackage{amsfonts}
\usepackage{xcolor}
\usepackage{listings}
\usepackage{textcomp}
\usepackage{setspace}
\usepackage{palatino}

\definecolor{green}{rgb}{0,0.5,0}

def __init__(self):

continue
else:

if fruitbowl is not None:

return
\end{python}
\begin{equation}

\end{document}

这样文档代码太长，可以拆分文件，为pythonlisting.tex + 主文件。语法文件这里下载：
http://cid-3cfe530319707374.office.live.com/self.aspx/ChinaTeX/pythonlisting.tex
那上面代码可以写为：

\documentclass{article}
\include{pythonlisting}
\begin{document}
