title: combine multiple lists horizontally into a single list
body: <p>I have searched up and down for this in python and could not find exactly what I'm looking for.</p>
  
  <p>Suppose I have the following example:</p>
  
  <pre><code>date_list = [Mar 27 2015, Mar 26 2015, Mar 25 2015]
  num_list_1 = [22, 35, 7]
  num_list_2 = [15, 12, 2]
  </code></pre>
  
  <p>How do I combine the lists so my end result is something like this:</p>
  
  <pre><code>combined_list = [Mar 27 2015, 22, 15
                   Mar 26 2015, 35, 12
                   Mar 25 2015, 7, 2]
  </code></pre>
  
  <p>Once I have the data in the combined_list variable, I want to be able to pass it to a for loop and iterate over each line and insert it into my SQLite db if the date does not exist or update the existing record if the date is found.</p>
  
  <p>I have my separate lists and I have the database insert working. What I'm not sure about is the proper way to combine the lists. Am I looking for a pandas dataframe?  Or something else?</p>
  
  <p>Any pointers to nudge me in the right direction would be appreciated</p>
