双列文档中的 Python 代码

Question

我想将我的 Python 代码放在一个两列文档中。我使用的listings包具有以下序言：

\usepackage{listings}
\usepackage{xcolor}
\definecolor{codegreen}{rgb}{0,0.6,0}
\definecolor{codegray}{rgb}{0.5,0.5,0.5}
\definecolor{codepurple}{rgb}{0.58,0,0.82}
\definecolor{backcolour}{rgb}{0.95,0.95,0.92}
\lstdefinestyle{mystyle}{
    backgroundcolor=\color{backcolour},   
    commentstyle=\color{codegreen},
    keywordstyle=\color{magenta},
    numberstyle=\tiny\color{codegray},
    stringstyle=\color{codepurple},
    basicstyle=\ttfamily\footnotesize,
    breakatwhitespace=true,         
    breaklines=true,                 
    captionpos=b,                    
    keepspaces=true,                                  
    showspaces=false,                
    showstringspaces=false,
    showtabs=false,                  
    tabsize=2
}
\lstset{style=mystyle}

我有 .py 文件的 python 代码，并且在正文中使用它，如下所示：

\lstinputlisting[language=Python]{<filename>.py}

但结果却如下图所示。

有没有办法将代码放在边距内？

Answer 1

以下重新格式化您的代码以轻松适应边距，并且是语法正确的 Python 代码。

\documentclass[twocolumn]{article}

\usepackage{listings}
\usepackage{xcolor}
\definecolor{codegreen}{rgb}{0,0.6,0}
\definecolor{codegray}{rgb}{0.5,0.5,0.5}
\definecolor{codepurple}{rgb}{0.58,0,0.82}
\definecolor{backcolour}{rgb}{0.95,0.95,0.92}
\lstdefinestyle{mystyle}{
    backgroundcolor=\color{backcolour},   
    commentstyle=\color{codegreen},
    keywordstyle=\color{magenta},
    numberstyle=\tiny\color{codegray},
    stringstyle=\color{codepurple},
    basicstyle=\ttfamily\footnotesize,
    breakatwhitespace=true,         
    breaklines=true,                 
    captionpos=b,                    
    keepspaces=true,                                  
    showspaces=false,                
    showstringspaces=false,
    showtabs=false,                  
    tabsize=2
}
\lstset{style=mystyle}

\begin{document}
\begin{lstlisting}
plt.errorbar(delay, TB, np.sqrt(TB/10))

i_max = np.argmax(TB)
print(delay[i_max])

plt.axvline(delay[i_max], linestyle='-',
            color='g', label='-2.5')

plt.xlabel('delay (ns)')
plt.ylabel('Coincidence rate (Hz)')
plt.legend()
plt.show()

GRA_coincidence = np.zeros(6)
GRA_coincidence_acc = np.zeros(6)
GRA_SNR = np.zeros(6)
GRA_SNR_error = np.zeros(6)
GRA_RB = np.zeros(6)
GRA_RT = np.zeros(6)
Racc = np.zeros(6)
plt.figure()
for i in range(6):
    A = '/content/coinc/coincidence' + \
        str(i + 1) + '.csv'
    res = read_gra(A)
    B = '/content/coinc/accidental' + \
        str(i + 1) + '.csv'
    res_acc = read_gra(B)
\end{lstlisting}
\end{document}
