Question

So here’s my code:

class Board:
    def __init__ (self, boardLength, boardHeight, pieces):
        self.__boardLength = boardLength
        self.__boardHeight = boardHeight
        self.__pieces = pieces
        self.__snapShots = []
        self.__tiles = []
        while len(self.__tiles) < (self.__boardHeight*self.__boardLength):
            self.__tiles.append(0)

board1 = Board(5, 4,
    [u,I_shape(1,'I'),X_shape(3,5,'U'),T_shape(4,5,'U'),L_shape(3,5,'U')]
)

and I get this:

TypeError: __init__() takes exactly 4 arguments (3 given)

I understand that init take 4 arguements, but one of them is self and I gave it the other three. Can anyone tell me what im doing wrong?

Answer 1

I imagine your problem is actually in I_shape, given your other shapes all take 3 arguments. I ran this and it worked fine, replacing the classes that don’t exist with None.

Also, it’s worth noting that using name mangling (__variable) is not needed 99.9% of the time. Use a single underscore if you want to indicate it’s private.
