title: I'm getting no such table <table name> error when i retrieve the data from sqlite? (Python 3.x)
body: <pre><code>import sqlite3 
  import pandas as pd
  a=sqlite3.connect('database.sqlite')
  b=pd.read_sql_query(''' SELECT * FROM Reviews ''',a)
  </code></pre>
  <p>Am I retrieving my data in a wrong way?  Please help me out! Whereas ,'Reviews' is name of the table and 'database.sqlite' is name of the file.</p>
