title: How could I check - does my SQLite3 database is empty?
body: <p>I am using Python 2.7 and SQLite3.
  When I starting work with DB I want to check - does my database is empty or on not. I mean does it already have any tables or not.</p>
  
  <p>My idea is to use the simple SELECT from any table. And wrap this select in try:exception block. So if exception was raised then my DB is empty.</p>
  
  <p>Maybe someone know the better way for checking?</p>
