如何在 LaTeX Listings \lstinputlistings 命令中突出显示 Python 语法
产生的答案来自红色模式，它给出了一个彩色的 Python 代码列表。尽管文本在此 Latex 代码中产生了减号/连字符。当我将它引入到我自己的代码中（如下）时，它没有。有人能帮我解决这个问题吗？我在 Ubuntu 20.04.1 LTS 上使用 TeXstudio 3.0.1。

好的方法是为编程语言定义新的环境。最低限度的设置可以围绕以下内容：
\documentclass[a4paper,12pt]{article}
\usepackage[utf8]{inputenc}
% Default fixed font does not support bold face
\DeclareFixedFont{\ttb}{T1}{txtt}{bx}{n}{12} % for bold
\DeclareFixedFont{\ttm}{T1}{txtt}{m}{n}{12} % for normal
% Custom colors
\usepackage{color}
\definecolor{deepblue}{rgb}{0,0,0.5}
\definecolor{deepred}{rgb}{0.6,0,0}
\definecolor{deepgreen}{rgb}{0,0.5,0}
\usepackage{listings}
% Python style for highlighting
\newcommand\pythonstyle{\lstset{
language=Python,
basicstyle=\ttm,
otherkeywords={self}, % Add keywords here
keywordstyle=\ttb\color{deepblue},
emph={MyClass,__init__}, % Custom highlighting
emphstyle=\ttb\color{deepred}, % Custom highlighting style
stringstyle=\color{deepgreen},
frame=tb, % Any extra options here
showstringspaces=false %
}}
% Python environment
\lstnewenvironment{python}[1][]
{
\pythonstyle
\lstset{#1}
}
{}
% Python for external files
\newcommand\pythonexternal[2][]{{
\pythonstyle
\lstinputlisting[#1]{#2}}}
% Python for inline
\newcommand\pythoninline[1]{{\pythonstyle\lstinline!#1!}}
\begin{document}
\section{``In-text'' listing highlighting}
\begin{python}
class MyClass(Yourclass):
def __init__(self, my, yours):
bla = '-5 1 2 3 -4'
-10
print bla
\end{python}
%\section{External listing highlighting}
%\pythonexternal{demo.py}
\section{Inline highlighting}
Definition \pythoninline{class MyClass} means \dots
\end{document}
这是我的乳胶代码，其中放置了上述代码，但没有显示减号。

我认为这是字体问题。使用 时\DeclareFixedFont{\ttm}{T1}{txtt}{m}{n}{12}，字体没有减号。我不确定你为什么不尝试类似
\newcommand\pythonstyle{\lstset{
language=Python,
basicstyle=\ttfamily,
otherkeywords={self}, % Add keywords here
keywordstyle=\ttb\color{deepblue},
emph={MyClass,__init__}, % Custom highlighting
emphstyle=\ttb\color{deepred}, % Custom highlighting style
stringstyle=\color{deepgreen},
frame=tb, % Any extra options here
showstringspaces=false %
}}
以防万一您不知道，该minted包在 的帮助下提供了更好的语法高亮结果pygments。
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{minted}
\usemintedstyle{manni}
\newmintinline[pyinl]{Python}{}
\begin{document}
\begin{minted}{python}
class MyClass(Yourclass):
def __init__(self, my, yours):
bla = '-5 1 2 3 -4'
-10
print bla
\end{minted}
\pyinl|class MyClass|
\end{document}
