I am making a really simple game where you make a table of numbers and hide a bomb that the use needs to find

Here is the code:

import random
def game(rows, colums):   
    table = (rows * colums - 1) * [' '] + ['bomb']    
    random.shuffle(table)    
    while True:    
        position = input('Enter next position (x, y):')    
        bombposition = position.split()    
        if table[int(bombposition[0])*colums + int(bombposition[1])] == 'bomb':    
            print('you found the bomb!')    
            break    
        else:    
            print('no bomb at', position) 

the error:

game(1,0)    
Enter next position (x, y):>?    
(1,0)    
Traceback (most recent call last):
