title: How to re-format a string (for a novice)
body: <p>A quick question from a Python novice... the short version is : How do I re-format a string like ('A', 'B', 'C') into ABC?</p>
  
  <p>Background: I'm writing a program that uses itertools.product to get all combinations of a set of letters <em>x</em> times. Eventually I want to search a much larger file to see how often each of those combinations occurs (<a href="https://stackoverflow.com/questions/533905/get-the-cartesian-product-of-a-series-of-lists-in-python">similar to this post</a>). So I need to ensure that the results from itertools.product are simply concatenated together, without the formatting characters and spaces. Each approach I've tried has failed or caused errors I don't know how to resolve. It seems like there'd be an easy way to do this...</p>
  
  <p>Can anyone help me find a way to take strings like
  ('A', 'B', 'C')
  and convert them to
  ABC?</p>
  
  <p>Thanks in advance for any assistance.</p>
