title: Stripping everything but alphanumeric chars from a string in Python
body: <p>What is the best way to strip all non alphanumeric characters from a string, using Python?</p>
  
  <p>The solutions presented in the <a href="https://stackoverflow.com/questions/840948">PHP variant of this question</a> will probably work with some minor adjustments, but don't seem very 'pythonic' to me.</p>
  
  <p>For the record, I don't just want to strip periods and commas  (and other punctuation), but also quotes, brackets, etc.</p>
