oh, thank you so much, sorry for the stupid error

nice kata! maybe too easy for 4 kyu, but still enjoyed resolving it, and very useful to train about oop

sorry for the stupid question, but what if a player ran out of cards in his hand? does he lose immediately? I think I don't understand...

sorry if i ask to you, but i updated a bit the code, and on my own it works, i think there are some strange cases that i can' handle, but i tried all the sample test and they work fine, can you give me an hint? :)

hi, when i try the code on my pc it works fine, but when i run it on codewars, it always return an IndexError: IndexError: too many indices for array, i can't figure out why. can someone help me?
this is my code:

import numpy as np
import warnings

warnings.filterwarnings('error')

class Sudoku(object):
	  def __init__(self, data):
		  self.data = data
	  def is_valid(self):
		  try:
			  arr = np.array(self.data)
			  arr.shape
		  except Warning:
			  return False
		  for row in self.data:
			  if len(set(row)) != len(row):
				  return False
		  for i in range(len(self.data)):
			  if len(set(arr[:, i])) != len(arr[:, i]):
				  return False
		  return True

yeah, thx, i fixed that, but it still doesn't work with a lot of random tests

hi everyone, i am struggling optimizing the algorithm, can someone send me some hints? :)
