need help with python check for win method:

current code:

import numpy as np

class Nim:

def $\_\_$init$\_\_($self$,$ piles, stones, limit$)$:

self.piles $=$ piles

self.stones $=$ stones

self.limit $=$ limit

self.winner $=$ None

self.turns $=0$

self.cur$\_$player $=1$

self.board $=[$stones$]*$ piles

def display$($self$)$:

print$($f$"$Current Turn: $\{$self$.$turns$\}$

Current Player: $\{$self$.$cur$\_$player$\}$

Piles: $\{$self$.$board$\}")$

Check for Win Method

The Nim class should have a check$\_$for$\_$win$()$ method. This method is used by the take$\_$action$()$ method

discussed below to determine if an action results in a victory for one of the players. The header for

check$\_$for$\_$win$()$ is shown below.

def check$\_$for$\_$win$($self$)$:

This method has only one parameter, self, which refers to the instance of Nim from which the method is being

called.

If all of the piles are empty, the method should set the value of the winner attribute equal to the cur$\_$player

attribute. The method does not need to return anything.
