title: Extracting multiple occurrences between 2 delimiters in a line
body: <p>How do we generically get the numbers into a list ?
  The delimiters may be "(" and ")", and it can be "[" and "]" or "{" and "}", or even "start" and "end", etc. </p>
  
  <pre><code>line = "-(123) = (456) = (789)-"
  
  result = re.findall(r"\([^']*\)", line)
  
  for i in result:
      print(i)
  </code></pre>
  
  <p>The numbers or any contents between the 2 delimiters are what we want to put in a list.</p>
