c = conn.cursor()
c.execute('select username,created from dba_users where username='USERNAME' ')
for row in c:
    print (row[0], '-', row[1]) # this only shows the first two columns. To add an additional column you'll need to add , '-', row[2], etc.
conn.close()

  File "*******************", line 9
    c.execute('select username,created from dba_users where username='MONITOR' ')
