Class confusion

[Rodrick Brown]

Can anyone care to advise on the following? Based on the responses does
this look sufficient?

#!/opt/local/bin/python

class SystemList(object):
    sysmap = { '1039' : 'nebula',
               '1040' : 'mercury'}

    def __init__(self, sysid):
        self.sysid = sysid

    def get_sysname(self):
        return self.sysmap[self.sysid]

class System(object):
    def __init__(self):
        pass

    def get_hostname(self,sysid):
        return  SystemList(sysid)

if __name__ == '__main__':
    sc = System()

    for sysid in ('1039','1040'):
        print(sc.get_hostname(sysid).get_sysname())
