title: Good Python modules for fuzzy string comparison?
body: <p>I'm looking for a Python module that can do simple fuzzy string comparisons.  Specifically, I'd like a percentage of how similar the strings are.  I know this is potentially subjective so I was hoping to find a library that can do positional comparisons as well as longest similar string matches, among other things.</p>
  
  <p>Basically, I'm hoping to find something that is simple enough to yield a single percentage while still configurable enough that I can specify what type of comparison(s) to do.</p>
