title: Multiply Values of two dictionaries, while appending the Keys in Python
body: <p>I have two dictionaries.
  One contain different products and each demand for them.
  The other contains a temporal demand distribution values in multiple days.</p>
  
  <p>I need to append the keys of both dictionaries, and multiply the demand by the temporal demand distribution.</p>
  
  <p>Sample Data (real data is much larger): </p>
  
  <pre><code> dict = {'S-NSW-BAC-ENG': 15, 'S-NSW-BAC-FBE': 30}
  
   temporal_demand_distibution = {-60: 0.001187, -59: 0.001354}
  </code></pre>
  
  <p>The expected output would be something like:</p>
  
  <pre><code>resulting_dict = {'S-NSW-BAC-ENG:-60': 0.001187*15, 'S-NSW-BAC-ENG:-59': 0.001354*15, 'S-NSW-BAC-FBE:-60': 30*0.001187, 'S-NSW-BAC-FBE:-59': 30*0.001354}
  </code></pre>
  
  <p>The values would obviously be the result of the multiplication and not the multiplication itself.</p>
  
  <p>I know it's bad to post a question without a sample code, but I have no idea how to achieve this.</p>
