title: Inserting an element at the first position in every individual list of a list of a list
body: <p>I have a simple problem. I need to insert an element from a list at the first position of every individual list, of a list of a list.</p>
  
  <p>I tried it using the code mentioned below but it doesn't give the required_output</p>
  
  <pre><code>for i in bank_name_list:
      for j in dummy_list:
          j.insert(0,i)
  print(dummy_list)
  </code></pre>
  
  <blockquote>
    <p>bank_name_list = ['Bank1', 'Bank2']</p>
    
    <p>dummy_list = [[2,4,5],[5,6,8]]</p>
    
    <p>actual_output = [['Bank2', 'Bank1', 2, 4, 5], ['Bank2', 'Bank1', 5, 6, 8]]</p>
    
    <p>required_output = [['Bank1',2,4,5],['Bank2',5,6,8]]</p>
