Re: [WINTCL] Dict and array

[Oleksiy B. <ole...@gm...>]

Thank you, Tobias and John for suggestions.

Actually, what I am seeking for is the way of representing
a multidimensional array of data for easy data store and retrieval.

Precisely speaking, I have the following data structure:

Parameters set 1:   ObjF_1: Case1(mxn matrix), Case2(mxn matrix), .....
                             ObjF_2: Case2(mxn matrix), .....
                             ObjF_n: .....

Parameters set 2: ObjF1: .......

Parameters set 3: ......

The idea is to store "Parameters set 1" as a dict variable, where ObjF_n is
also dict with keys CaseN, and CaseN in turn is an array where every name
represent a row of the matrix.

So, probably the nested dicts fit my need.

Thank you again for the explanation on dict type variable.
