title: How can I extract the maximum values along the horizontal and vertical from the coordinates of the grid using python?
body: <p>I was calculating the points of intersections from a grid. I want to use these points for further analysis like annotating the positions of the points of intersections on an image.</p>
  <pre><code>[(65, 1),(132, 1),(198, 1),(265, 1),(332, 1),(399, 1),(466, 1),(533, 1),(600, 1),(666, 1),(732, 1),(799, 1),(865, 1),(931, 1),(997, 1),(1063, 1),(1130, 1),(1196, 1),(65, 67),(132, 67)]
  </code></pre>
  <p>How can I obtain the maximum for the x-axis and y-axis in that list of coordinates?</p>
  <p>The expected results are as follows</p>
  <pre><code>max_x = 1196
  max_y = 67
  </code></pre>
  <p>Thank you so much</p>
