Suppose I have a Unicode character, and I want to determine the script or

For example:
U+0033 DIGIT THREE "3" belongs to the script "COMMON";
U+0061 LATIN SMALL LETTER A "a" belongs to the script "LATIN";
U+03BE GREEK SMALL LETTER XI "ΞΎ" belongs to the script "GREEK".
Is this information available from Python?
More about Unicode scripts:

Interestingly, there's issue 6331 "Add unicode script info to the
unicode database". Looks like it didn't make it into Python 3.6.
https://bugs.python.org/issue6331
Opened in 2009 with patch and 2 revisions for 2.x. At least the Python
code needs to be updated.
Approved in principle by Martin, then unicodedata curator, but no longer
active. Neither, very much, are the other 2 listed in the Expert's index.
From what I could see, both the Python API (there is no doc patch yet)
and internal implementation need more work. If I were to get involved,
I would look at the APIs of PyICU (see Eryk Sun's post) and the
unicodescript module on PyPI (mention by Pander Musubi, on the issue).
