如何跳过列表中带有点的行？

Question

我想知道包是否listings具有可以跳过几行并用一些点替换它们的功能，以产生类似以下内容

1 | error_temp = 错误 - ((numpy.linalg.norm(b，'fro')) ** 2.0)

... | ...

5 | 错误 -= (numpy.linalg.norm(b[j, :])) ** 2.0

我希望能够指定几行并要求listings用点替换它们，同时打印几个点作为行号以指示它在这里跳过了几行。此外，当跳过结束时，恢复到实际的行号，就好像没有跳过跳过的行一样。

这是我的最小工作示例，但可能没有帮助

\documentclass{article}
\usepackage{listings}
\lstset{breaklines = true, frame = trBL, tabsize = 4, basicstyle = \small \ttfamily, keywordstyle = \color{blue}, stringstyle = \color{red}, rulecolor = \color{black}, numbers = left, numberstyle = \tiny}

\begin{document}

\begin{lstlisting}[language = Python, escapeinside = {(*@}{@*)}]
error_temp = error - ((numpy.linalg.norm(b, 'fro')) ** 2.0)
(*@ \cdots @*)
error -= (numpy.linalg.norm(b[j, :])) ** 2.0
\end{lstlisting}

\end{document}

代码的问题是，它不会跳过行号，也不能打印点作为跳过行的行号。

如果您不清楚我要做什么，请告诉我，提前谢谢您！

对此进行一些修改回答，也许会用到以下代码。

\documentclass{article}
\usepackage{listings,xcolor}
\lstset{breaklines = true, frame = trBL, tabsize = 4, basicstyle = \small \ttfamily, keywordstyle = \color{blue}, stringstyle = \color{red}, rulecolor = \color{black}, numbers = left, numberstyle = \tiny}

\let\origthelstnumber\thelstnumber
\makeatletter
\newcommand*\Suppressnumber{%
  \lst@AddToHook{OnNewLine}{%
    \let\thelstnumber\relax%
  }%
}

\newcommand*\Reactivatenumber{%
  \lst@AddToHook{OnNewLine}{%
   \let\thelstnumber\origthelstnumber%
  }%
}
\makeatother

\begin{document}

\begin{lstlisting}[language = Python,escapeinside=||]
error_temp = error - ((numpy.linalg.norm(b, 'fro')) ** 2.0)|\Suppressnumber|
 ... 
 ...
 ...|\Reactivatenumber|
error -= (numpy.linalg.norm(b[j, :])) ** 2.0
\end{lstlisting}

\end{document}

附录： 行号表示它正在跳过行。

\documentclass{article}
\usepackage{listings,xcolor}
\lstset{breaklines = true, frame = trBL, tabsize = 4, basicstyle = \small \ttfamily, keywordstyle = \color{blue}, stringstyle = \color{red}, rulecolor = \color{black}, numbers = left, numberstyle = \tiny}

\let\origthelstnumber\thelstnumber
\makeatletter
\newcommand*\Suppressnumber{%
  \lst@AddToHook{OnNewLine}{%
    \let\thelstnumber\relax%
  }%
}

\newcommand*\Reactivatenumber{%
  \lst@AddToHook{OnNewLine}{%
   \let\thelstnumber\origthelstnumber%
  }%
}
\makeatother

\begin{document}

\begin{lstlisting}[language = Python,escapeinside=||]
error_temp = error - ((numpy.linalg.norm(b, 'fro')) ** 2.0)|\Suppressnumber|
 |\thelstnumber|
 |\thelstnumber|
 |\thelstnumber||\Reactivatenumber|
error -= (numpy.linalg.norm(b[j, :])) ** 2.0
error -= (numpy.linalg.norm(b[j, :])) ** 2.0
\end{lstlisting}

\end{document}
