body: <p>I want to convert a variable from object to integer</p>
  
  <pre><code>mapper = dict('А Б' = 0 , 'Г Д' = 1)
  SyntaxError: keyword can't be an expression
  </code></pre>
  
  <p>'А Б' , 'Г Д' - russian letters. 
  What is correct way to convert a variable from object to integer?
  Both python 3.5 or 2.7</p>
