According to an experienced Acrobat user on https://community.adobe.com/t5/acrobat-sdk-discussions/how-can-one-embed-or-call-some-python-code-in-a-acrobat-javascript-script/m-p/12712912#M88574, it's not possible to embed or call some Python code in an Acrobat JavaScript script. I'm guessing the only solution is attempting to convert the python code into some JavaScript that Acrobat understands.
