Split a zip-file into chunks with Python

Question

I have a piece of a code which creates a zip file successfully, but I need to split this file if the size of it is more that 1MB.

I have this code but it doesn't work:

    from split_file_reader.split_file_writer import SplitFileWriter
    import zipfile

    # make element tree
    tree = etree.ElementTree(batch_element)

    # make xml file and write it in stream
    xml_object = BytesIO()
    tree.write(xml_object, pretty_print=True, xml_declaration=False, encoding="utf-8")
    xml_file = xml_object.getvalue()

    final = BytesIO()

    with SplitFileWriter(final, 1_000_000) as sfw:
        with zipfile.ZipFile(sfw, "a") as zip_file:
            zip_file.writestr('Batch.xml', xml_file)

I want to retrieve the split file as bytes. The zipping part is working, but the splitting doesn't.

Read the docs for the module which you are using, which is https://pypi.org/project/split-file-reader

It should have the usage instructions in there.

EDIT: This is an example:

with SplitFileWriter("split.zip.", 500_000) as sfw:
    with zipfile.ZipFile(file=sfw, mode='w') as zipf:
        for root, dirs, files in os.walk("./"):
            for file in files:
                if file.startswith("random_payload"):
                    zipf.write(os.path.join(root, file))
