Finally, write a method __eq__(self, other) that overloads the == operator creating a version of the operator that works for Board objects. The method should return True if the called object (self) and the argument (other) have the same values for the tilesattribute, and False otherwise.

This method should be straightforward to implement because you can simply use the ==operator to compare self.tiles and other.tiles. You do not need to explicitly compare the individual tiles yourself, because the == operator already compares the individual elements of 2-D lists.

Examples:

>>> b1 = Board('012345678') >>> b2 = Board('012345678') >>> b1 == b2 True >>> b2.move_blank('right') True >>> b1 == b2 False
