[Zope-dev] string functions - need a how-to... joining two properties

[Digital Hyakugei]

And, again, questions...

lets say i have some properties that i want to concatenate. they are both 
int's (or not, i'm sure i will want to do this with strings too at some 
point) that i would like to cast to strings.

propA = 1
propB = 2

lets say that i want to be able to do something like

propC = string(propA) + string(propB)

which should result in

propC = "12"

I've *read* about string.join() but am unable to make it work...
Any help would be great!!!
thanks again!
