Hi Manu, Currently, we use Python 3.5.2 on Jenkins for testing. Python tests print out the python version in the console logs and I found this information from one of the logs [1]. Initial proposal for the Python 3 support was to support a specific version of python 3 during the porting process and later on work to add support for additional versions [2]. (Also note that, Python 3 was released about 3 months ago and after the porting effort started.)
Hope this helps.
