Write all pythonq contents in an external python file

[jowe19]

Hi,
I'd like to be able sometimes to run some code directly in a Python editor.

Is it possible to write the contents of pythonq environments to an external python file ? (if there are several pythonq, the code will be added to the previous python file). I don't know if it's possible to do this easily with pyluatex.

Suggestion

\documentclass{article}

\usepackage{pyluatex}

\directlua{file = io.open("pythonq_output.py", "w")}
\AtEndDocument{\directlua{file:close()}}

% \string is required for TeX not to interpret \n as TeX command
% On Windows you might need an additional \r
\AddToHook{env/pythonq/after}{%
    \directlua{file:write(table.concat(pyluatex.get_last_code(), "\string\n") .. "\string\n")}}

\begin{document}
\begin{pythonq}
    a = 5
    b = 7
\end{pythonq}
\begin{pythonq}
    c = 9
\end{pythonq}

\py{a + b + c}
\end{document}

Content of pythonq_output.py after the TeX run:

    a = 5
    b = 7
    c = 9
