title: How to replace characters in strings without the Python re library
body: <p>I am able to replace characters in strings using the Python re library, but I need to use the pyparsing library (or no library at all) instead. Is there another way to do this without re?</p>
  
  <pre><code>import re
  string = re.sub(r'[\t\r\n]', '', string)
  </code></pre>
