title: zip list too many items to unpack
body: <p>i have a zipped list with 13 lists. I would like to insert the items into a mysql database. here is my code:</p>
  
  <pre><code>zipped_list=zip(list1,list2...list13)
  for a,b,c,d,e,f,g,h,i,j,k,l,m in zipped_list:
      cur.execute("INSERT INTO QB_global_sentiment(%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s) VALUES('%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s','%s')" %("date","US_pos","US_neg","US_neu","UK_pos","UK_neg","UK_neu","CA_pos","CA_neg","CA_neu","AU_pos","AU_neg","AU_neu",str(m), str(a),str(b),str(c),str(d),str(e),str(f),str(g),str(h),str(i),str(j),str(k),str(l)))
  </code></pre>
  
  <p>This is my error:</p>
  
  <pre><code>    for a,b,c,d,e,f,g,h,i,j,k,l,m in zipped_list:
  ValueError: too many values to unpack
  </code></pre>
  
  <p>I agree there is too many items and its really long..is there a better way to do this?</p>
  
  <p>Thanks!</p>
