更改 LaTeX 文件中 Python 程式碼的大小

Question

我正在嘗試使用以下命令在文件中輸入我的 Python 程式碼這模板使用了清單包裹。不過，我想更改程式碼字體的大小，即任何提及的內容\texttt{}和lstlisting環境。

\documentclass[12pt]{article}
\usepackage[T1]{fontenc}
\usepackage{fourier}

\usepackage[scaled]{beramono}
\usepackage{listings}
\lstset{
  language=Python, showstringspaces=false, formfeed=\newpage, tabsize=4,
  commentstyle=\itshape, basicstyle=\ttfamily, morekeywords={models, lambda, forms}
  fontsize=\footnotesize
}
\newcommand{\code}[2]{
  \hrulefill
  \subsection*{#1}
  \lstinputlisting{#2}
  \vspace{2em}
}

\begin{document}

This is the code from my file \texttt{mycode.py}:

\begin{lstlisting}
def factorial(n):
   """The factorial of a number the slow way"""

   # comments are printed in italic
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)
\end{lstlisting}


\end{document}

我嘗試fontsize=\footnotesize在序言中放入不同的位置，但這不起作用。有什麼建議麼？

Answer 1

添加：\footnotesizebasicstyle

\documentclass[12pt]{article}
\usepackage[T1]{fontenc}
\usepackage{fourier}

\usepackage[scaled]{beramono}
\usepackage{listings}
\lstset{
  language=Python,
  showstringspaces=false,
  formfeed=\newpage,
  tabsize=4,
  commentstyle=\itshape,
  basicstyle=\ttfamily\footnotesize,
  morekeywords={models, lambda, forms},
}
\newcommand{\code}[2]{%
  \hrulefill
  \subsection*{#1}%
  \lstinputlisting{#2}%
  \vspace{2em}%
}

\begin{document}

This is the code from my file \texttt{mycode.py}:

\begin{lstlisting}
def factorial(n):
    """The factorial of a number the slow way"""

    # comments are printed in italic
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)
\end{lstlisting}


\end{document}

然而，您也應該進一步縮小 Bera Mono 的規模；在這種情況下，\footnotesize似乎沒有必要。

\documentclass[12pt]{article}
\usepackage[T1]{fontenc}
\usepackage{fourier}

\usepackage[scaled=0.8]{beramono}
\usepackage{listings}
\lstset{
  language=Python,
  showstringspaces=false,
  formfeed=\newpage,
  tabsize=4,
  commentstyle=\itshape,
  basicstyle=\ttfamily\footnotesize,
  morekeywords={models, lambda, forms},
}
\newcommand{\code}[2]{%
  \hrulefill
  \subsection*{#1}%
  \lstinputlisting{#2}%
  \vspace{2em}%
}

\begin{document}

This is the code from my file \texttt{mycode.py}:

\begin{lstlisting}
def factorial(n):
    """The factorial of a number the slow way"""

    # comments are printed in italic
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)
\end{lstlisting}


\end{document}
