@ in python code with minted

Question

I want to add some python code using the minted package to my latex file. I used

\begin{minted}
[
frame=lines,
framesep=2mm,
baselinestretch=1.2,
fontsize=\footnotesize,
linenos
]
{python}
A @ B
\end{minted}

which worked until now that I have some @ in my code (I am new here and don't know how to add the compiled version). The @ will display with a red box around them. Does someone know how to get rid of this red box?

Answer 1

The python lexer thinks the syntax A @ B is an error. Instead you can use the python3 lexer, which does accept it:

\documentclass{article}
\usepackage{minted}
\begin{document}
\begin{minted}
[
frame=lines,
framesep=2mm,
baselinestretch=1.2,
fontsize=\footnotesize,
linenos
]
%%% python3 instead of python
{python3}
A @ B
\end{minted}
\end{document}

Answer 2

One more solution I found is to change the style of minted to something that does not show errors. Go to https://pygments.org/demo/#try and try the different styles for the code. The style "xcode" for example would work in this case. Then just type

\usemintedstyle{xcode}

or input any other style.
