title: Python Nested list function to return score for students exam's.
body: <p>I am trying to write a function named studentGrades(gradeList) that takes a nested list and returns a list with the average score for each student. 
  An example would be:</p>
  
  <pre><code> grades= [['Student','Quiz 1','Quiz 2','Quiz 3','Final'],
   ['John', 100, 90, 80, 90],
   ['McVay', 88, 99, 11, 15],
   ['Rita', 45, 56, 67, 89],
   ['Ketan', 59, 61, 67, 32],
   ['Saranya', 73, 79, 83, 45],
   ['Min', 89, 97, 101, 100]]
   studentGrades(grades)
  
   # Sample output below
   &gt;&gt;&gt; [90, 53, 64, 54, 70, 96]
  </code></pre>
  
  <p>I don't know how to do this using a nested loop. Any help or guidance is appreciated. </p>
