I'm afraid my code might be a little unclear as well :)

This isn't in complete conformity with the specification in my first
post, but you'll get the idea. In my real program I'll be generating a
lot of results and I don't need to keep them for long. The result gets
printed to a file immediately. Then I can throw it away and get the next
result. I think it is nicer to generate the result object in the called
method. But I'm worried about the penalities.


######################### first solution 
class foo:
    def __init__(self, data):
        foo.data = data
        
    def getresult(self, inresult):
        inresult.data = self.data * 5


class result:
    def __init__(self):
        self.data = 0

foo_object = foo(10)
result_object = result() ##################    the resultobject is
generated in the calling code 
foo_object.getresult(result_object)
print result_object.data
#will print 50
    
######################### second solution 

class foo:
    def __init__(self):
        foo.data = 0
        
    def getresult(self):
        newresult = result() #############     the result object is
generated in the called method
        newresult.data = self.data * 5
        return newresult


class result:
    def __init__(self):
        self.data = 0

foo_object = foo()
foo_object.data = 10

result_object = foo_object.getresult()
print result_object.data
#will print 50
