The alignment of the caption of the my lstlistings environment for code is not correct when inside lists.
The code to generate the image is given in the working example...

\begin{document}
Below is how this should look...
\begin{lstcode}[language=Python,caption={Listings Example}]
print("Hello") # comment
\end{lstcode}
\begin{itemize}
\item Item text above the code
\begin{lstcode}[language=Python,caption={Listings Example}]
print("Hello") # comment
\end{lstcode}
\end{itemize}
\end{document}
How can I fix this?
UPDATE
I found out I can wrap these in a tcolorbox environment,eg...
\begin{tcolorbox}[width=\textwidth, breakable, standard jigsaw, opacityback=0, frame hidden, sharp corners, enhanced, boxrule=0pt]
\begin{lstcode}[language=Python,caption={Listings Example}]
print("Hello World")
\end{lstcode}
\end{tcolorbox}
Is there a way to combine both of these into a singular code environment (w/out using tcblistings)?
I tried...
\usepackage{etoolbox}
\BeforeBeginEnvironment{lstcode}{\begin{tcolorbox}[size=fbox,breakable, standard jigsaw, opacityback=0, frame hidden, sharp corners, enhanced, boxrule=0pt]}
\AfterEndEnvironment{lstcode}{\end{tcolorbox}}
and ended up w/ a working example...

\begin{lstcode}[language=Python, caption={Hello World Example}]

print("Hello World")
\end{lstcode}
\end{itemize}
\end{itemize}
\end{itemize}
\end{document}
and the output...
So now I just need to fix the indentation and extra lines of code under lists...
UPDATE
The alignment issue goes away when I put the above fix in my actual document. The last problem problem is that the top of the tcolorbox is too big when there is a caption (shown below w/ frame).
How can I fix this?
