title: Python 3 Input to 2D List
body: <p>I'm trying to get input of 3 numbers, then save them into a 2-D list.</p>
  
  <p>ex. </p>
  
  <pre><code>Input: 1 2 3
  Input: 4 5 6
  Input: 7 8 9
  
  = [[1,2,3], [4,5,6], [7,8,9]]
  </code></pre>
  
  <p>When I try to add the inputs to a list I get this:</p>
  
  <pre><code>['1 2 3', '4 5 6', '7 8 9']
  </code></pre>
  
  
  
  <pre><code>myList=[]
  in=input("3 numbers:")
  myList.append(in)
  
  while in!= "":
      in=input("Enter 3 numbers: ")
      in.split()
      myList.append(in)
  </code></pre>
  
  <p>I need them to be integers too so I can do maths with them later but I have no idea how to do that and save the inputs to a 2d list at the same time.</p>
