[Python] How to get the total size of a public MEGA folder URL using python

I want to get the total size of all files in a public MEGA folder, given its URL (with decryption key), using Python only. Example: https://mega.nz/folder/...

I tried using mega.py, but it doesn't seem to support public folders, only public file links.

python
Python 3.11.0 (main, Oct 24 2022, 18:26:48) [MSC v.1933 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from mega import Mega
>>> mega = Mega()
>>> m = mega.login('username', 'passwrod')
>>> link = "https://mega.nz/folder/[link]#[key]"
>>> link_info = m.get_public_url_info(link)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "...\AppData\Local\Programs\Python\Python311\Lib\site-packages\mega\mega.py", line 990, in get_public_url_info
file_handle, file_key = self._parse_url(url).split('!')
^^^^^^^^^^^^^^^^^^^^
File "...\AppData\Local\Programs\Python\Python311\Lib\site-packages\mega\mega.py", line 206, in _parse_url
raise RequestError('Url key missing')
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "...\AppData\Local\Programs\Python\Python311\Lib\site-packages\mega\errors.py", line 58, in __init__
code_desc, long_desc = _CODE_TO_DESCRIPTIONS

Código:

                           ~~~~~~~~~~~~~~~~~~~~~^^^^^^
KeyError: 'Url key missing'

>>> link = "https://mega.nz/file/[link]#[key]"
>>> link_info = m.get_public_url_info(link)
>>> print(link_info)
{'size': 6732143421, 'name': 'Name.mp4'}


The documentation for mega.py is here: [URL]https://github.com/odwyersoftware/mega.py[/URL]

From the code, the _parse_url method only supports parsing file URLs, not folder URLs. Here’s the relevant snippet:

def _parse_url(self, url):
    """Parse file id and key from url."""
    if '/file/' in url:
        # V2 URL structure
        url = url.replace(' ', '')
        file_id = re.findall(r'\W\w\w\w\w\w\w\w\w\W', url)[0][1:-1]
        id_index = re.search(file_id, url).end()
        key = url[id_index + 1:]
        return f'{file_id}!{key}'
    elif '!' in url:
        # V1 URL structure
        match = re.findall(r'/#!(.*)', url)
        path = match[0]
        return path
    else:
        raise RequestError('Url key missing')


I tried other tools like: mega-cmd, rclone, megatool,etc... but none seem to support getting the size of a public folder URL.

Also, The official mega-cmd documentation is here: [URL]https://github.com/meganz/MEGAcmd[/URL] I haven’t found support for public folder size queries either.

Is there any Python based way to get the file sizes from a public folder?

Thanks in advance.
