title: Python string.strip stripping too many characters
body: <p>I am using Python 3 to process file names, and this is my code:</p>
  
  <pre><code>name = 'movies.csv'
  table_name = name.strip(".csv")
  </code></pre>
  
  <p>The expected value of table_name should be "movies" yet table_name keeps returning "movie".</p>
  
  <p>Why is it doing this?</p>
