>>> def mkTriPart(a,b,c): return "%d.%d.%d" %(a,b,c)
>>> def splitTriPart(n): return map(int,n.split('.'))
>>>
>>> yrs = 42
>>> mnth = 11
>>> days = 7
>>> age = mkTriPart(yrs,mnth,days)
>>> print age
'42.11.7'
>>> y = splitTriPart(age)
>>> print "Yrs: %d  Mnths: %d  Days: %d" % (y[0],y[1],y[2])
Yrs: 42  Mnths: 11  Days: 7
>>> Maj = 2
>>> Min = 1
>>> Rev = 123
>>> vers = mkTriPart(Maj,Min,Rev)
>>> etc...

That kind of thing?
