[Tutor] Question about lists

[Leo Degon]

I'm trying to create a class where the main focus is creating a list whose
elements are lists and the elements of those lists are collection of zeros
and ones. I am trying to create functions to rotate the list ninety
degrees, to reflect it. Having a few problems with the rotation.
get TypeError: 'list' object is not callable

def pset(n):
    for i in n:
        print(i)
class board():
    def make(self,size):
        b=[]
        for i in range(size[0]):
            b.append([])
            for j in range(size[1]):
                b[i].append(0)
        return b

    def rotate(self,board,size):
        size[0],size[1]=size[1],size[0]
        new=board(size)
        lists=[]
        for j in range(size[1]):
            lists.append([])
            for i in range(size[0]).__reversed__():
                lists[j].append(board[i][j])
        for i in range(size[1]):
            for j in range(size[0]):
                new.board[i,j]=lists[i,j]
        return(new.board)
    def __init__(self,size):
        self.size=size
        self.board=self.make(size)
y=[7,7]
x=board(y)
pset(x.board)
x.board[0][0]=1
print()
pset(x.board)
print()
x.board=x.rotate(x.board,x.size)
pset(x.board)
print()
