yes and yes. both item and subitem are created on the spot; anychunk of 
python code like:
for x in y:
will create x as a variable and with each iteration x refers to the next 
item in y;
Of course if I knew the function of the list/dictionary I'd name them 
something more informative than item and subitem - like f.e. for lap in 
d and for time in d if it was refering to races.
