The unicode version for my debian9 is 9.0-1 ?

For unicode version in python3

>>> import unicodedata
>>> unicodedata.unidata_version
'8.0.0'

Does it mean that unicode version in my debian9 is 9.0-1 ,different from unicode version in my python3?

Answer 1

Python doesn't use system unicodedata. It is compiled an existing set. If you check the below url

https://docs.python.org/3.5/library/unicodedata.html

This module provides access to the Unicode Character Database (UCD) which defines character properties for all Unicode characters. The data contained in this database is compiled from the UCD version 8.0.0.

and for Python 3.6.5

https://docs.python.org/3.6/library/unicodedata.html

This module provides access to the Unicode Character Database (UCD) which defines character properties for all Unicode characters. The data contained in this database is compiled from the UCD version 9.0.0.

So its just that your system python version is not on 3.6.X and that is why you see a 8.0.0
