title: What's best way to take input of more than 1 list in python?
body: <p>I need to put user input in list like:</p>
  
  <pre><code>11 20
  22 30
  32 45
  34 54
  .. ..
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>for i in range(n):
      c, d = map(int, input().split())
      a.append(c)
      b.append(d)
  </code></pre>
  
  <p>Is there any better way than this?</p>
