title: How to remove elements from a Python dictionary based on elements in a list?
body: <p>I have a list of tuples:</p>
  
  <pre><code>lst=[(6, 'C'), (6, 'H'), (2, 'C'), (2, 'H')]
  </code></pre>
  
  <p>And a dictionary:</p>
  
  <pre><code>dct={'6C': (6, 'C'), '6H': (6, 'H'), '9D': (9, 'D'), '10D': (10, 'D'), '11S': (11, 'S'), '2C': (2, 'C'), '2H': (2, 'H')}
  </code></pre>
  
  <p>How can I remove the elements from the dictionary that are in the list? In this example my desired output would be: </p>
  
  <pre><code>dct2={'9D': (9, 'D'), '10D': (10, 'D'), '11S': (11, 'S')}
  </code></pre>
