title: from pandas dataframe save csv file without double quotes
body: <p>To save a csv file from pandas dataframe I have tried following way:</p>
  
  <pre><code>res.to_csv('seq_test.fa',header= False, index= False, sep = '\t', quoting = csv.QUOTE_NONE)
  </code></pre>
  
  <p>and this gives me following error:<code>need to escape, but no escapechar set</code></p>
  
  <p>If I don't use <code>quoting = csv.QUOTE_NONE</code> . I get output below way:</p>
  
  <pre><code>&gt;His-ATG-1-1    33-35
  "TGGGGTATAGCTCCATGGTAGAGCGCATGCCTATGAAGCGTGAGGTCCTGGGTTTGATCCCCAGAACCACAACCA
  "   
  &gt;Pro-AGG-2-1    33-35
  "GGCTTGTTGGTCTAGGGGTATGATTCTCACTTAGGGTGTGAGAGGTCCTGGGTTCAAATCTTGGACGAGTCCCCA
  "   
  &gt;Lys-TTT-1-1    34-36

  "   
  &gt;Ile-TAT-3-1    34-36
  "GGTTCCATAGGGTAGTGGTTATCACATCTGCTTTATATGCAGAAGGTCCTGAGTTTGAGCCCCAGTGGAACTACCA
  "
  </code></pre>
  
  <p>Here I don't want any double quotes in my output.
  Can someone suggest me any possible way?
  If anycase required I am using pandas version 0.17 on python 2.7</p>
