how can get the unicode version in my python3.4?

Question

The latest unicode version is Unicode 7, according to http://www.unicode.org/versions/ .

Which Unicode version was python3.4 built on? How to get it?

Answer 1

From the unicodedata module documentation for Python 3.4 :

The data contained in this database is compiled from the UCD version 6.3.0.

The unicodedata.unidata_version value tells you the version used your current Python installation; demo on Python 3.4:

>>> import unicodedata
>>> unicodedata.unidata_version
'6.3.0'

Python 3.5 (first alpha due out in February 2015 ) will use Unicode 7.0.0.
