python - How to call attributes from outside classes? -

updated 2.0

currently updated every old "function" has been moved beneath class. seems 1 of problems figuring out these drawboard() takes 1 positional argument 2 given

this start of current class, show dealing

update based on:

every run of program give option size board should ... every board in code shall same size

we make size class variable , prompt size if isn't set. subsequent board creations use same size first board:

class boardhandler:     size = none      def __init__(self):         self.board = none          if boardhandler.size none:             self.ask_size()          self.getnewboard()      def ask_size(self):  # no self use, method function         while true:             try:                 boardhandler.size = int(input("which size want? "))                 break             except valueerror:                 print("wrong! try again")      def getnewboard(self):         self.board = []          _ in range(boardhandler.size):             self.board.append([' '] * boardhandler.size)      def resetboard(self):         x in range(boardhandler.size):             y in range(boardhandler.size):                 self.board[x][y] = ' '          n = int(boardhandler.size / 2 - 1)         self.board[n][n] = 'b'         self.board[n + 1][n] = 'w'         self.board[n][n + 1] = 'w'         self.board[n + 1][n + 1] = 'b'      def drawboard(self):         hline = '   ' + '-' * (4 * boardhandler.size) + '-'          print(hline)          y in range(boardhandler.size):             print("{:2d}".format(y + 1), end=' ')             x in range(boardhandler.size):                 print('| {}'.format(self.board[x][y]), end=' ')             print('|')             print(hline)  handler = boardhandler() handler.resetboard()  handler.board[0][0] = 'w'  handler.drawboard()  print(boardhandler.size)  handler2 = boardhandler() handler2.drawboard()  # empty board same size first
