title: Append Column From One Df to Another Based on lists of indexes - pandas
body: <p>I have a list of indexes for two data frames.</p>
  
  <p>For <code>df1</code>,</p>
  
  <pre><code>df1_ind_list = [2,4,6]
  </code></pre>
  
  <p>For <code>df2</code></p>
  
  <pre><code>df2_ind_list = [0,2,5]
  </code></pre>
  
  <p>These are my Data Frames, <code>df1</code>,</p>
  
  <pre><code>   Name     Net        Quantity  
  0  Auto     1010       10
  1  NaN      NaN        12
  2  Rtal     4145       18
  3  NaN      NaN        14
  4  Indl     6223       16
  5  NaN      7222       18
  6  lkr      6584       13
  7  trml     9854       45
  </code></pre>
  
  <p>my <code>df2</code></p>
  
  <pre><code>   Cust     COT         DHL  
  0  plot     2020        10,12
  1  nnjd     4645        18,14
  2  pplr     5643        16,18
  3  kkll     8755        89,20
  4  hjot     8754        96,23
  5  llrm     9855        16,65
  6  pollr    8758        33,52
  </code></pre>
  
  <p>Now, I want to bring in values to my <code>df1</code> from <code>df2</code> to based on the index list. Output should be,</p>
  
  <pre><code>       Name     Net    Quantity   Cust   COT   DHL
      0  Auto     1010       10     NaN    NaN   NaN
      1  NaN      NaN        12     NaN    NaN   NaN
      2  Rtal     4145       18     plot   2020  10,12
      3  NaN      NaN        14     NaN    NaN   NaN
      4  Indl     6223       16     pplr   5643  16,18
      5  NaN      7222       18     NaN    NaN   NaN
      6  lkr      6584       13     llrm   9855  16,65
      7  trml     9854       45     NaN    NaN   NaN
  </code></pre>
  
  <p>Is there a pandas way to do append into the index? I don't know how to go about this, any help/idea would be great. </p>
