关键思想

如何将python代码块中的数字颜色改为蓝色，但同时让注释块中的数字保留绿色？

另外，对于关键字network3。如何将关键字“network3”更改为蓝色，但在“network3.load_data_shared()”中将“network3”保留为黑色？

以下是代码：

\documentclass[a4paper, 10pt, oneside, fleqn, openright]{report}
\usepackage[no-math]{fontspec}

\usepackage{calc}
\usepackage[usenames,dvipsnames,svgnames,table]{xcolor}
\usepackage{pdfpages,graphicx}
\usepackage{mdframed}
\usepackage{listings}

\definecolor{light-gray}{gray}{0.92}
\definecolor{mainColor}{RGB}{211, 47, 47} % some dark red

\renewcommand\lstlistingname{Python Code}
\lstdefinestyle{pycode}{
    language=Python,
    numbers=left,
    numbersep= 7mm,
    numberstyle=\color{Black},
    stepnumber=1,
    tabsize=3,
    breakatwhitespace=false,
    breaklines=true,
    captionpos=b,
    basicstyle=\color{Black}\ttfamily,
    commentstyle=\color{LimeGreen},
    stringstyle=\color{WildStrawberry},
    frame=leftline,
    framesep=0mm,
    xleftmargin=3mm,
    framesep=2mm,
    framerule=0mm,
    abovecaptionskip=5mm,
    aboveskip=\baselineskip,
    belowskip=\baselineskip,
    basicstyle=\ttfamily\scriptsize,
    classoffset=1,
    morekeywords={var, func, extends, import, as,from},
    keywordstyle=\color{BurntOrange}\bfseries,
    classoffset=2,
    morekeywords={network3},
    keywordstyle=\color{blue}\bfseries,
}

答案1

这是解决评论问题的一种方法。它不是完全自动化的，因为你需要突出显示评论片段，但只要这不是常规做法，那么你应该没问题。（这是基于这个答案到继续列表包中的行号？）。这种方法有几个明显的缺陷，但作为一种快速破解方法，它可能是合适的。

关键思想

  1. 将代码分为注释块和非注释块（这不是完全自动化的）。为此，我创建了一个\begin{brokenlst}环境来使用。
  2. \begin{pycode}然后逐个输入代码块。
  3. 应该对代码块进行命名，以确保它知道是否应该选择并继续编号。
  4. 通过切换来标记这是否是注释还是常规块或代码style。

新变化

请注意以下事项：

\makeatletter
\lstnewenvironment{pycode}[1][]{%
\lstset{%
#1,
%...
%numberstyle=\color{black}, % Removed
%...
aboveskip=-0.5\baselineskip, % Changed
%belowskip=-0.\baselineskip, % Removed
%...
}%
\csname\@lst @SetFirstNumber\endcsname
}{%
\csname \@lst @SaveFirstNumber\endcsname
}
\makeatother

\lstdefinestyle{comment}{numberstyle=\color{magenta}}

\newenvironment{brokenlst}{\addvspace\baselineskip}{\addvspace\baselineskip}

We begin with some broken code 

\begin{brokenlst}
\begin{pycode}[name=ForLoopBlock, style=comment]
# echo xyz
\end{pycode}
\begin{pycode}[name=ForLoopBlock]
for i in range(10):
print('Hello world')
\end{pycode}
\begin{pycode}[name=ForLoopBlock, style=comment]
# x = 2
\end{pycode}
\begin{pycode}[name=ForLoopBlock, caption={Some broken code.}]
for i in range(10):
print('Hello world') # Why?
\end{pycode}
\end{brokenlst}


Some other unrelated code

\begin{brokenlst}
\begin{pycode}[name=Something else]
for i in range(10):
    print('Hello world')
\end{pycode}
\end{brokenlst}

The user's code snippet.

\begin{brokenlst}
\begin{pycode}[name=ManyPlots, style=comment]
"""
===============
Many plot types can be combined in one figure to create
powerful and flexible representations of data.
10 is not colored.
"""
\end{pycode}
\begin{pycode}[name=ManyPlots, caption={Doesn't look too bad \dots}]

import network3
from network3 import Network
from network3 import ConvPoolLayer, FullyConnectedLayer, SoftmaxLayer
training_data, validation_data, test_data = network3.load_data_shared()
mini_batch_size = 10
net = Network([
FullyConnectedLayer(n_in=784, n_out=100),
SoftmaxLayer(n_in=100, n_out=10)], mini_batch_size)
net.SGD(training_data, 60, mini_batch_size, 0.1, validation_data, test_data)
\end{pycode}
\end{brokenlst}

Other languages shouldn't be too effected. 
\begin{lstlisting}[language=c, caption={Perhaps revise your default listing name?}]
int main()
{
    printf("hello world")
}
\end{lstlisting}
