You can also use read and write files instead of Python strings. For 
example, if you have a `notebookify` function that takes a doc (pandoc AST) 
and returns a Jupyter notebook (as a Python JSON-like dictionnary), your 
wrapper script could be something like:

# file: notebookify.py

# here: imports, notebookify definition, etc.
# ...

def main():
    filename = sys.argv[1]
    doc = pandoc.read(file=filename)

    notebook = notebookify(doc)

    ipynb = Path(filename).with_suffix(".ipynb")
    with open(ipynb, "w", encoding="utf-8") as output:
        json.dump(notebook, output, ensure_ascii=False, indent=2)

if __name__ == "__main__":
    main()

you would invoke it with

$ python notebookify.py my_document.md

and it would produce a my_document.ipynb Jupyter notebook.

This example is developped with more details here:
