OP solved it, closing

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

Not a kata issue, you use a var with the same name as the function. Use let to keep the scope (and probably it's not a best practice to name two different things the same).

clever

Yes, you run out of cards, you lose. The winner is the player that ends up with all the cards.

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...

for the rest of the test cases did you TLE? because seems like the parts that go "array[a][b] not in res" is going to be O(n-squared) time complexity due to searching through the whole array every time you try to put something in.

if its TLE, try to think of a faster algo?

Good first step is to reproduce failing test cases locally and debug them in your IDE: https://github.com/codewars/codewars.com/wiki/Troubleshooting-your-solution#how-can-i-see-which-input-causes-my-solution-to-fail

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? :)

the shape isn't the only problem. I guess you should read a bit more about sudokus. Maybe solve some by hand too.

not an issue a question (since the problem is in your code, not in the kata)

I'd bet on global variables in your code, that are interacting from one test to the other.

Post your code with a spoiler flag if needed.

Closing the issue aspect,
Cheers

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
