title: List Comprehensions: How do I crank out a new list for every loop iteration of x where an item in both "lists" match?
body: <pre><code>allDasTickets = ["9255955", "9255958", "9255960", "9255977"]
  [j for j in allDasTickets for x in allDasTickets if x != j]
  </code></pre>
  
  <p>So I get an list of the following lists:</p>
  
  <pre><code>['9255958', '9255960', '9255977']
  ['9255955', '9255958', '9255977']
  ['9255958', '9255960', '9255977']
  ['9255955', '9255958', '9255960']
  </code></pre>
  
  <p>i.e. a list with the matching one missing (I hope that's what I've put above)</p>
