title: Is there a pythonic way to insert space characters at random positions of an existing string?
body: <p>is there a pythonic way to implement this:</p>
  
  <blockquote>
    <p>Insert <code>/spaces_1/</code> <code>U+0020 SPACE</code>
    characters into <code>/key_1/</code> at random
    positions other than the start or end
    of the string.</p>
  </blockquote>
  
  <p>?</p>
  
  <p>There <code>/spaces_1/</code> is integer and <code>/key_1/</code> is arbitrary existing string.</p>
  
  <p>Thanks.</p>
