title: Python write 2 lists and Pandas DataFrames to csv/excel sequentially
body: <p>I have these Python lists and Pandas Dataframes:</p>
  
  <pre><code>list_1 = ['Intro line here - record of method function:']
  list_2 = ['Record of local minimum follows:']
  
  print df_1
     Col_A    Col_B
    3.4443    1.443
   10.8876    11.99
  
  print df2
  Trial_1  Trial_2  Trial_3
      1.1     1.49    775.9
     11.5     9.57     87.3
   384.61   77.964     63.7
    12.49    0.156      1.9
   112.11   11.847    178.3
  </code></pre>
  
  <p>Here is what I want in the output csv or excel file - either csv or excel would work for me:</p>
  
  <pre><code>Intro line here - record of method function:
     Col_A    Col_B
    3.4443    1.443
   10.8876    11.99
  Record of local minimum follows:
  Trial_1  Trial_2  Trial_3
      1.1     1.49    775.9
     11.5     9.57     87.3
   384.61   77.964     63.7
    12.49    0.156      1.9
   112.11   11.847    178.3
  </code></pre>
  
  <p>Is there a way to write the list, Pandas, list, Pandas in this order to the csv or excel file?</p>
