hi all! my problem is: I have (for example) 2 sets of quantity set(A,B,C) or set(A,B,D). I need to calculate another quantity E which is function of A,B,C or A,F. but F in turn is function of (A,B,D). I want to write one function that checks the supplied set if it possible to calculate requested the value depending on the set of values supplied, it should check what input data it needs and call functions in tree-like manner to check which quantity can they provide. In reality dependecies of course deeper sets are longer and data are very big arrays (do not fit into memory of my machine), another reason is easy to extend the program if I will need a function indirectly depending on already existed.
the question is: maybe there is a design template for this? what I invented now is bit ugly... thanks Maxim Loginov _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
