Write a module of utility functions called util.py for manipulating 2-dimensional arrays of size 4x4 in python 3.4

The functions you need to write are as follows:

def create_grid(grid):

"""create a 4x4 array of zeroes within grid"""

def print_grid (grid):

"""print out a 4x4 grid in 5-width columns within a box"""

def check_lost (grid):

"""return True if there are no 0 values and there are no adjacent values that are equal; otherwise False"""

def check_won (grid):

"""return True if a value>=32 is found in the grid; otherwise False"""

def copy_grid (grid):

"""return a copy of the given grid"""

def grid_equal (grid1, grid2):

"""check if 2 grids are equal - return boolean value"""

this is testutil:

def run_test (test):
if test == 0:
grid = []
util.create_grid (grid)
print (len (grid))
print (len (grid[0]))
print (len (grid[1]))

print (grid[1][2])
print (grid[2][1])
print (grid[3][3])
