title: Snowflake not getting connected via python
body: <p>I am trying to run a small piece of code to connect snowflake via python but I get the following error, I saw few documentations from the snowflake community but the answers don't seem to be convincing because it did not do much help. I will paste my code here, please let me know how you can help on this issue.</p>
  
  <p>Code:</p>
  
  <pre><code>import snowflake.connector
  
  conn = snowflake.connector.connect(user='domainname\username',password=password,account='account.region.snowflakecomputing.com',warehouse='dpt',database='dpt_test2',schema='qa')
  
  cur = conn.cursor()
  
  cur.execute("select * from customer")
  
  print (cur.fetchone()[0])
  
  conn.close()
  </code></pre>
  
  <p>Error:</p>
  
  <blockquote>

  <p>in case I remove snowflake.computing.com from the account parameter I get an incorrect user name and password.</p>
