Ich versuche, lstlistingPython-Code mit benutzerdefiniertem Format zu verwenden. Das Problem besteht darin, dass einige Wörter als Schlüsselwörter erkannt werden, obwohl ich sie nicht als solche haben möchte. Ich habe versucht, den Befehl zu verwenden, deletekeywordsaber ohne Erfolg.
Das Folgende ist ein McVe-Tex-Dokument, das mein Problem reproduziert: Die Wörter applyund hashwerden in Blau angezeigt, der den Schlüsselwörtern zugewiesenen Farbe.

Die Datei lstlang1.sty(verwenden Sie den Befehl, kpsewhich lstlang1.styum sie zu finden) enthält die Definition der Python-Sprachen für listings. Die Schlüsselwörter sind in zwei Gruppen definiert:
morekeywords={access, and, break, class, continue, def, del, elif, else,%
except, exec, finally, for, from, global, if, import, in, is, lambda,%
not, or, pass, print, raise, return, try, while},%
% Built-ins
morekeywords=[2]{abs, all, any, basestring, bin, bool, bytearray,%
callable, chr, classmethod, cmp, compile, complex, delattr, dict, dir,%
divmod, enumerate, eval, execfile, file, filter, float, format,%
frozenset, getattr, globals, hasattr, hash, help, hex, id, input, int,%
isinstance, issubclass, iter, len, list, locals, long, map, max,%
memoryview, min, next, object, oct, open, ord, pow, property, range,%
raw_input, reduce, reload, repr, reversed, round, set, setattr, slice,%
sorted, staticmethod, str, sum, super, tuple, type, unichr, unicode,%
vars, xrange, zip, apply, buffer, coerce, intern},%
Die Schlüsselwörter applyund hashgehören zur zweiten Gruppe. Um sie zu löschen, müssen Sie Folgendes verwenden:
deletekeywords=[2]{hash,apply},
Hier ist Ihr korrigierter MWE (mit einem Komma am EndejedeSchlüssel):

Nun, ich glaube, ich kenne Ihr Problem. Sie denken, „deletekeywords“ löscht ein vordefiniertes Schlüsselwort, aber tatsächlich löscht es ein Schlüsselwort aus der benutzerdefinierten Liste, die Sie in „morekeywords“ erstellt haben.
Leider würde für mich nur funktionieren, einen benutzerdefinierten Stil für Python von Grund auf neu zu definieren und dabei das zu verwenden, was Sie bereits haben. Anschließend sollten Sie die gewünschten Schlüsselwörter manuell in „morekeywords“ hinzufügen.
\lstdefinestyle{pythoncode}{
language={}, %You shall leave this blank
tabsize=4,
caption={Python function to split between train and test sets.},
label={lst:code_direct},
literate={~} {$\sim$}{1},
backgroundcolor=\color{white},
basicstyle=\footnotesize,
breakatwhitespace=false,
captionpos=b,
morecomment=[l]{##},
commentstyle=\color{gray}\textit,
escapeinside={\%*}{*)},
extendedchars=true,
frame=tb,
keepspaces=true,
keywordstyle=\color{blue}\bfseries,
morekeywords={return,def,apply,lambda}, %New keywords
numbers=left,
numbersep=5pt,
numberstyle=\tiny\color{gray},
rulecolor=\color{black},
showspaces=false,
showstringspaces=false,
showtabs=false,
stepnumber=1,
stringstyle=\ttb\color{red},
tabsize=2,
title=\lstname,
columns=fixed,
emph ={split_train_test_by_id, test_set_check},
emphstyle=\color{red}}
Um diesen Stil zu verwenden, verwenden Sie
\begin{lstlisting}[style=pythoncode]
**Your Python Code here**
\end{lstlisting}
Es ist wahrscheinlich nicht das Beste, aber es sollte funktionieren, solange jemand eine bessere Antwort hat.
