清单中忽略了 Python“as”关键字

Question

以下代码无法高亮作为关键字。我做错了什么？不应该作为大胆一点进口？

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{listings}

\lstset{morekeywords={as}}

\title{Python listings}
\author{me}

\begin{document}

\maketitle

\section{Introduction}
Python example

\begin{lstlisting}[language=Python]
#!/usr/bin/env python
"""
An animated image
"""
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
\end{lstlisting}

done with the example.
\end{document}

Answer 1

morekeyword=as如果您声明该选项，则该选项有效后告知listings要使用的语言是 Python：

\documentclass{article}
\usepackage{listings}

\begin{document}
\begin{lstlisting}[language=Python,morekeywords=as]
#!/usr/bin/env python
"""
An animated image
"""
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
\end{lstlisting}
\end{document}

为 Python 定义一个自己的环境可能更好：

\lstnewenvironment{Python}[1][]
  {\lstset{language=Python,
           morekeywords=as,
           #1}%
  }
  {}

这样就可以写

\begin{Python}
<Python code>
\end{Python}

可能会提供其他本地选择，比如

\begin{Python}[basicfamily=\ttfamily]
<Python code>
\end{Python}
