title: Can lists be mutated?
body: <p>When I type following code,</p>
  
  <pre><code>x=[1,2,4]
  print(x)
  print("x",id(x))
  x=[2,5,3]
  print(x)
  print("x",id(x))
  </code></pre>
  
  <p>it gives the output as </p>
  
  <pre><code>[1, 2, 4]
  x 47606160
  [2, 5, 3]
  x 47578768
  </code></pre>
  
  <p>If lists are mutable then why it give 2 memory address when changing the list x?</p>
