That indeed seems very strange. When I run it I see the correct version:

% python3.5
Python 3.5.3 (default, Apr 23 2017, 18:09:27)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Is /opt/local/bin/python3.5 somehow a link to a different version? Does 
uninstalling and reinstalling python35 help?
