Odoo 12.0 does *not* officially support any python version below 3.5, but no effort had been made to gracefully announce this to the end user if they were to run Odoo in an unsupported python version. This is done because Odoo 12.0 uses py3-only constructs which can and will raise different errors if ran in python 2. With this patch, Odoo will display an appropriate error message and won't launch at all unless it is being run with python 3.5 or greater. closes odoo/odoo#28502
