如何为列表添加嵌套标题

我想重新创建嵌套的列表标题，如下图所示，我尝试这样做：

\documentclass{article}
\usepackage{listings}
\usepackage{subcaption}

\begin{document}

\lstlistoflistings

\section{Example Python programs}

Here are two example Python programs that print "Hello, World!":

\begin{figure}[htbp]
  \centering
  \begin{subfigure}[b]{0.45\textwidth}
    \begin{lstlisting}[language=Python,caption={[First program] Python program to print "Hello, World!"},label={lst:hello1}]
      print("Hello, World!")
    \end{lstlisting}
  \end{subfigure}
  \hfill
  \begin{subfigure}[b]{0.45\textwidth}
    \begin{lstlisting}[language=Python,caption={[Second program] Python program to print "Hello, World!"},label={lst:hello2}]
      print("Hello, World!")
    \end{lstlisting}
  \end{subfigure}
  \caption{Example Python programs.}
  \label{fig:example}
\end{figure}

We can reference the first program using Listing \ref{lst:hello1}, and the second program using Listing \ref{lst:hello2}.

\end{document}

但是，这样会创建两个并排的列表。任何帮助都非常感谢。

这使用了 lstlisting 自定义标题。

\documentclass{article}
\usepackage{listings}
\usepackage{newfloat}

%\renewcommand{\lstlistingname}{Sublisting}
\DeclareFloatingEnvironment[fileext=lol,listname=Listings,name=Listing,placement=htp]{listing}

\usepackage{caption}
\captionsetup[listing]{position=above}
\AtBeginDocument{\counterwithin{lstlisting}{listing}}% not defined earlier

\begin{document}

\listoflistings

\section{Example Python programs}

Here are two example Python programs that print "Hello, World!":

\begin{listing}
  \caption{Example Python programs.}% must be above
  \label{fig:example}
  
    \begin{lstlisting}[language=Python,caption={[First program] Python program to print "Hello, World!"},label={lst:hello1}]
      print("Hello, World!")
    \end{lstlisting}
    
    \begin{lstlisting}[language=Python,caption={[Second program] Python program to print "Hello, World!"},label={lst:hello2}]
      print("Hello, World!")
    \end{lstlisting}
\end{listing}

We can reference the first program using Listing \ref{lst:hello1}, and the second program using Listing \ref{lst:hello2}.

\end{document}

这使用\subcaption。请注意，lstlisting计数器不会增加。

\documentclass{article}
\usepackage{listings}
\usepackage{newfloat}

\renewcommand{\lstlistingname}{Sublisting}

\DeclareFloatingEnvironment[fileext=lol,listname=Listings,name=Listing,placement=htp]{listing}

\usepackage{subcaption}
\captionsetup[listing]{position=above}
\DeclareCaptionSubType{listing}
\renewcommand{\thesublisting}{\thelisting.\arabic{sublisting}}
\captionsetup[sublisting]{singlelinecheck=off,labelformat=simple,labelsep=colon,skip=0pt,list=true}
\def\sublistingname{Listing}

\begin{document}

\listoflistings

\section{Example Python programs}

Here are two example Python programs that print ``Hello, World!'':

\begin{listing}
  \caption{Example Python programs.}% must to above
  \label{fig:example}
    \subcaption[First program]{Python program to print ``Hello, World!''}\label{lst:hello1}
    \begin{lstlisting}[language=Python]
      print("Hello, World!")
    \end{lstlisting}
    
    \subcaption[Second program]{Python program to print "Hello, World!"}\label{lst:hello2}
      
    \begin{lstlisting}[language=Python]
      print("Hello, World!")
    \end{lstlisting}
\end{listing}

We can reference the first program using Listing \ref{lst:hello1}, and the second program using Listing \ref{lst:hello2}.

\end{document}
