title: Removing Trailing Comma from Query result in Robot Framework
body: <p>I am extracting data from MySQL that returns query results as follows:</p>
  
  <pre><code>    ${A} = (('HFL', 'TCFLORWWGMAFVFEQLVRN', 'ZZG', 1625, 'SA,WE,DN_IS,', 84))
  </code></pre>
  
  <p>In this part 'SA,WE,DN_IS,' the trailing Comma needs to be removed for data validation. I am using robot framework for this and created loops to extract data from the list and compare individual elements with data on the webpage. So far I did not find any method in Robot Framework, specially Collections Library that I can use to remove the trailing comma. Is there any way to remove it using Robot Framework? Thanks in advance for your help.  </p>
