title: Delete a specific occurrence of an integer in multiple lists at once. Python
body: <pre><code>mike = [1, 2, 3, 4,]
  john = [2, 3, 4, 5,]
  adam = [3, 4, 5, 6,]
  joey = [4, 5, 6, 7,]
  
  employees = [mike, john, adam, joey]
  </code></pre>
  
  <p>When an element from the employees list is removed, how would you delete the variable with the same name, and a specific element in all of the lists?</p>
  
  <p>For example, if [mike] was removed from 'employees'...the mike variable needs to be deleted, and the integer "1" deleted from ALL of the lists.</p>
