nsoffer pushed a commit to branch master
in repository sanlock.

commit 8bf78b8468d21d9adca78235e6e29a2235589e08
Author: Nir Soffer <nsoffer(a)redhat.com&gt;
AuthorDate: Sun Jun 16 17:47:52 2019 +0300

    python: Convert example.py to python 3
    
    Use print function instead of print statement to make the example
    compatible with both python 2 and 3. Tested only by flake8, may not
    actually work with python 3.
