Bonjour à tous - je suis débutant avec latex.
Dans un questionnaire je souhaite avoir l'opinion de candidats sur un bout de code.
Je vous fournis l'exemple suivant (qui est aussi en pj)

L'erreur renvoyée est :

! LaTeX Error: There's no line here to end.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

l.44 ...scoring{1}\correctchoice[J]{j}\scoring{2}}

Le segment de code concerné est :

\begin{question}{Q0}
Que vaut var apres ces deux lignes
\begin{lstlisting}
def f():
    print('Lorem')
\end{lstlisting}
%Décommenter et cela fonctionne 
\AMCOpen{lines=2}{\wrongchoice[F]{f}\scoring{0}\wrongchoice[P]{p}\scoring{1}\correctchoice[J]{j}\scoring{2}}
\end{question}

À toute fin utile je joint les contenus du document et de la sortie standard.

%Pour illuster le probleme de nouvelle ligne avec un lsiting python
