Hoi, I have the following data structure (of variable size actually, to make things simple, just that one): d = {'a': {'x':[1,2,3], 'y':[4,5,6]}, 'b': {'x':[7,8,9], 'y':[10,11,12]}} This can be read as a dict of possibilities: The entities 'a' and 'b' have the parameters 'x' and 'y', each. And d['a']['x'] can be either 1 or 2 or 3. Does anybody know a convenient (and fast) way to permute over all possible nested dicts like {'a': {'x':1, 'y':4}, 'b': {'x':7, 'y':10}} and {'a': {'x':2, 'y':4}, 'b': {'x':7, 'y':10}} and so forth?
Any link or snippet is appreciated. TIA Christian -- http://mail.python.org/mailman/listinfo/python-list
