I am typesetting code using minted or listings package. It works fine. Now I am hoping to add a label, similar to equation label, on the left side of the code block, looks like following. (%o1) is the label.

However, I can't find a way to do this. Any hint will be appreciated.

 I would think the simplest is to put the code listing in a list item, eg
 \usepackage{enumitem,listings}
...
\begin{enumerate}[label={(\%ol)}]
\item \begin{lstlisting}
foo
bar
\end{lstlisting}
\end{enumerate}
 That way (enumitem) you have good control over the label and the spacing.

Thank you very much. The code in your reply is exactly what I need. It is simple and robust (I think).
I'm just getting back to you because my last test (for some reason) didn't work, but today it did. It's really weird.
Best,
