title: How to remove "Decimal" from the query result
body: <p>I have result from PostgreSQL query using the following code:</p>
  
  <pre><code>cur = con.cursor()
  cur.execute("""SELECT to_char(tt.service_date,'yyyy-mm-01') AS txn_month,
          SUM (tt.customer) AS customer,SUM (tt.tour) AS tour,
          SUM (tt.distancetraveled) AS distancetraveled
      FROM
          tbl_travel as tt
      GROUP BY
          txn_month""")
  rows = cur.fetchall()
  </code></pre>
  
  <p>My query result is something like this:</p>
  
  <pre><code>[('2016-01-01', Decimal('11.0909090909090909'), Decimal('3.7272727272727273'), 58.5354545454545),
   ('2016-02-01', Decimal('11.6666666666666667'), Decimal('4.0000000000000000'), 74.8766666666667)]
  </code></pre>
  
  <p>I need to remove the "Decimal" string in front of the values and get result like:</p>
  
  <pre><code>[('2016-01-01', '11.0909090909090909', '3.7272727272727273','58.5354545454545'),
   ('2016-02-01', '11.6666666666666667', '4.0000000000000000','74.8766666666667')]
  </code></pre>
