3 0 1   ->   3 0 1
3 0 1   ->   3 0 X
0 2 1   ->   0 X X
0 2 0   ->   0 X 0

expected is:

{ 'sunk': 1, 'damaged': 1 , 'not_touched': 1, 'points': 0.5}"
   ship 2      ship 1          ship 3

which seems pretty much consistent to me. ;)

not correct. ;) Read again the part that explains how to use the attacks coordinates (that's not any usual use of them)
