title: python: cleaning up a string
body: <p>i have a string like this</p>
  
  <pre><code>somestring='in this/ string / i have many. interesting.occurrences of {different chars} that need     to .be removed  '
  </code></pre>
  
  <p>here is the result i want:</p>
  
  <pre><code>somestring='in this string i have many interesting occurrences of different chars that need to be removed'
  </code></pre>
  
  <p>i started to manually do all kinds of <code>.replace</code>, but there are so many different combinations that i think there must be a simpler way. perhaps there's a library that already does this?</p>
  
  <p>does anyone know how i can clean up this string>?</p>
