title: Removing unwanted characters from a string in Python
body: <p>I have some strings that I want to delete some unwanted characters from them.
  For example: <code>Adam'sApple ----&gt; AdamsApple</code>.(case insensitive)
  Can someone help me, I need the fastest way to do it, cause I have a couple of millions of records that have to be polished.
  Thanks</p>
