title: Importing init_db (flask tutorial)
body: <p>I have been through the tutorial on flask (http://flask.pocoo.org/docs/tutorial/introduction/)</p>
  
  <p>And now I am getting errors, can you help me please? :)</p>
  
  <p>On github it says this in the readme... (https://github.com/mitsuhiko/flask/tree/master/examples/flaskr/)</p>
  
  <pre><code>fire up a python shell and run this:
  
  from flaskr import init_db; init_db()
  </code></pre>
  
  <p>So I open my python shell and type it in... Only problem is that I get an import error saying it cannot find flaskr...</p>
  
  <p>If I try run the flaskr.py file locally I just get this</p>
  
  <pre><code>sqlite3.OperationalError OperationalError: unable to open database file
  </code></pre>
  
  <p>I am really new to this and python in general so any help would be great, thank you.</p>
