title: Why does randint not work in a matrix but everywhere else? (Noob Python)
body: <p>I've been making a seating chart in Python that displays absences in the place of each seat. To make a list of example absences I decided to use randint to generate a random value between 0-15 but when I try it in the matrix it doesn't work. However the same line used outside the matrix and just printed worked fine.. How do I fix this?</p>
  
  <p>Here is my code:</p>
  
  <pre><code>import random
  
  student0Abs_EX = random.randint(0,15)
  student1Abs_EX = random.randint(0,15)
  student2Abs_EX = random.randint(0,15)
  student3Abs_EX = random.randint(0,15)
  student4Abs_EX = random.randint(0,15)
  student5Abs_EX = random.randint(0,15)
  student6Abs_EX = random.randint(0,15)
  student7Abs_EX = random.randint(0,15)
  student8Abs_EX = random.randint(0,15)
  student9Abs_EX = random.randint(0,15)
  
  print("\n\nExample Absences: \n")
  matrix = [[student0Abs_EX + '\t\t', student1Abs_EX + '\t\t', student2Abs_EX + '\t\t'], [student3Abs_EX + '\t\t', student4Abs_EX + '\t\t', student5Abs_EX + '\t\t'], [student6Abs_EX + '\t\t', 'Empty' + '\t\t', student7Abs_EX + '\t\t'], ['Empty' + '\t\t', student8Abs_EX+ '\t\t', student9Abs_EX + '\t\t']]
  for row in matrix:
      print ' '.join(row)
  </code></pre>
  
  <p>Thanks in advance for any help!</p>
