title: Python Quick Question about writing a dataframe to csv-Naming conventions
body: <p>I have to read a table every 30 minutes and I have made the query which only takes updates rows.</p>
  
  <pre><code>dfsql = client.query(sql, project=project_id).to_dataframe()
  </code></pre>
  
  <p>I have already existing table when I created dataframe for the first time using this</p>
  
  <pre><code>dfsql.to_csv('/home/analytics/divyang/divyangtest.csv')
  </code></pre>
  
  <p>Now,I want to write the updated records into a new table (not in divyangtest.csv) so each time my query runs, I should have a new table like divyangtest1,divyangtest2 etc</p>
