title: Printing a string prints 'u' before the string in Python?
body: <p>'u' before elements in printed list? I didn't type u in my code.</p>
  
  <pre><code>hobbies = []
  
  #prompt user three times for hobbies
  for i in range(3):
      hobby = raw_input('Enter a hobby:')
      hobbies.append(hobby)
  
  #print list stored in hobbies
  print hobbies
  </code></pre>
  
  <p>When I run this, it prints the list but it is formatted like this:</p>
  
  <pre><code>Enter a hobby: Painting
  Enter a hobby: Stargazing
  Enter a hobby: Reading
  [u'Painting', u'Stargazing', u'Reading']
  None
  </code></pre>
  
  <p>Where did those 'u' come from before each of the elements of the list?</p>
