Use a class variable:
class baseClass:
hostName = None # undefined yet
def someFunc(self):
assert self.hostName is not None, "hostname not set yet"
... # use hostName here
class temp(baseClass):
def runTest(self):
baseClass.hostName = getHostName()
...
or a global variable:
baseClass.py:
hostName = None
class baseClass:
def someFunc(self):
assert hostName is not None
....
testme.py:
import baseClass
class temp(baseClass.baseClass):
....
baseClass.hostName = getHostName()
although neither solution strikes me as very elegant. I would normally pass
the hostname to the constructor of baseClass or use a separate 'settings'
module.
Global variables are per-module. Use the "global" keyword when assigning a
global variable in the 'current' module. Global variables of other modules
are properties of the module, use <module>.<name>.

Yes. Don't worry, the work is done only once.
