title: Python: count repeated elements in the list
body: <p>I am new to Python. I am trying to find a simple way of getting a count of the number of elements repeated in a list e.g.</p>
  
  <pre><code>MyList = ["a", "b", "a", "c", "c", "a", "c"]
  </code></pre>
  
  <p>Output:</p>
  
  <pre><code>a: 3
  b: 1
  c: 3
  </code></pre>
