title: Removing words with special characters "\" and "/"
body: <p>During the analysis of tweets, I run in the "words" that have either \ or / (could have more than one appearance in one "word"). I would like to have such words removed completely but can not quite nail this</p>
  
  <p>This is what I tried:</p>
  
  <pre><code>sen = 'this is \re\store and b\\fre'
  sen1 = 'this i\s /re/store and b//fre/'
  
  slash_back =  r'(?:[\w_]+\\[\w_]+)'
  slash_fwd = r'(?:[\w_]+/+[\w_]+)'
  slash_all = r'(?&lt;!\S)[a-z-]+(?=[,.!?:;]?(?!\S))'
  
  strt = re.sub(slash_back,"",sen)
  strt1 = re.sub(slash_fwd,"",sen1)
  strt2 = re.sub(slash_all,"",sen1)
  print strt
  print strt1
  print strt2
  </code></pre>
  
  <p>I would like to get:</p>
  
  <pre><code>this is and
  this i\s and
  this and
  </code></pre>
  
  <p>However, I receive:</p>
  
  <pre><code>and 
  this i\s / and /
  i\s /re/store  b//fre/
  </code></pre>
  
  <p>To add: in this scenario the "word" is a string separated either by spaces or punctuation signs (like a regular text)</p>
