SDK API to get the version of openstack distribution

Hi, I am able to iterate through the list of hypervisors and servers as follows. for hypervisor in self.connection.list_hypervisors(): for server in self.connection.compute.servers(): However, I could not find an API that returns the version of the OpenStack i.e. whether it is Stein, Train, or Ussuri. Openstack CLI client has command: openstack versions show Thanks, /anil.
