Can someone help me out with this Python assignment?

"The task is to create a simple Battleship class in Python and test it. A ship has the properties start_x, start_y, length, direction and amount of hits. A ship must have following methods.

- A constructor that makes the ship. It should take values of all the the qualities except amount of hits as parameters. You can use the length 2 and direction horizontal as default values. Amount of hits should be set to 0. A __str__ method that makes and returns a string that should as a minimum contain start coordinates, length and amount of hits.

- A method hit() that registers that the ship has been hit through increasing the hit quality by 1.

- A method is_sunk that returns True if the ship has sunk and False if not

You have to make this class as well as a if__name__ == <<__main__>>: block that tests it through making at least two ships with different lenghts and shoots at them with hits() until they sink, but not further."
