title: How do I modify this regex to not match '&' in Python?
body: <p><strong>Background</strong></p>
  
  <p>I would like to extract a piece of information out of a string. For example,</p>
  
  <p>NO PARKING (SANITATION BROOM SYMBOL) 8-9:30AM TUES &amp; FRI</p>
  
  <p>Because it's only <code>TUES</code> and <code>FRI</code>. It's not a range of days so I would like to just get <code>['TUES', 'FRI']</code> </p>
  
  <p>However, for something like </p>
  
  <pre><code>2 HOUR PARKING 9AM-5PM MON THRU SAT
  </code></pre>
  
  <p>It would be a range of days so the result would be 
  <code>['MON', 'TUES', 'WED', 'THURS', 'FRI', 'SAT']</code></p>
  
  <p>I have this regex which works with a range of days but I would like to modify to except just one rule. </p>
  
  <pre><code>\b((?:(?:MON|MONDAY|TUES|TUESDAY|WED|WEDNESDAY|THURS|THURSDAY|FRI|FRIDAY|SAT|SATURDAY|SUN|SUNDAY)\s*)+)(?=\s|$)
  </code></pre>
  
  <p>It works with </p>
  
  <pre><code>NO STANDING 11AM-7AM MON SAT
  </code></pre>
  
  <p>which extracts <code>MON</code> and <code>SAT</code>. But I don't want it to match</p>
  
  <pre><code>NO PARKING (SANITATION BROOM SYMBOL) 8-9:30AM TUES &amp; FRI
  </code></pre>
  
  <p>Because I have another regex which I want it to be matched. </p>
