title: Assigning one list to another
body: <pre><code>listOne = [1, 2, 3]
  listTwo = listOne
  
  print(listOne) #[1, 2, 3]
  
  listTwo.append(4)
  
  print(listOne) #[1, 2, 3, 4]
  print(listtwo) #[1, 2, 3, 4]
  </code></pre>
  
  <p>Here my doubt is that we are assigning listOne to list two. That is listTwo is pointing to listOne. So when we append the value to listTwo why is it reflecting in listOne as well? I am new to python. Please help me out.</p>
