title: how do i code a module of utility functions called util.py for manipulating 2-dimensional arrays of size 4x4?
body: <h1>skeleton for the code</h1>
  <p>The functions you need to write are as follows:
  def create grid(grid):
  &quot;&quot;&quot;create a 4x4 array of zeroes within grid&quot;&quot;&quot;
  def print grid (grid):
  &quot;&quot;&quot;print out a 4x4 grid in 5-width columns within a box&quot;&quot;&quot;
  def check lost (grid):
  &quot;&quot;&quot;return True if there are no 0 values and there are no
  adjacent values that are equal; otherwise False&quot;&quot;&quot;
  def check won (grid):
  &quot;&quot;&quot;return True if a value&gt;=32 is found in the grid; otherwise
  False&quot;&quot;&quot;
  def copy grid (grid):
  &quot;&quot;&quot;return a copy of the given grid&quot;&quot;&quot;
  def grid equal (grid1, grid2):
  &quot;&quot;&quot;check if 2 grids are equal - return boolean value&quot;&quot;&quot;</p>
