title: Randomly selecting a character and 4 subsequent characters from a string
body: <p>Given the following string</p>
  <pre><code>string = 'SATSUNMONTUEWEDTHUFRI'
  </code></pre>
  <p>If I wanted to randomly select a character/s I can accomplish that using <code>random.choices()</code> For example, here I'm selecting 5 characters</p>
  <pre><code>rs = random.choices(string, k = 5)
  </code></pre>
  <p>But, what if I wanted to select 5 subsequent characters. One possible result is:</p>
  <pre><code>[SATSU]
  </code></pre>
  <p>How can I accomplish this?</p>
