title: No string after Escape Sequences '\b'
body: <p>why <code>print('abcd\b')</code> is <code>abcd</code> Instead of <code>abc</code></p>
  
  <p>it is working if we put space after \b</p>
  
  <pre><code>&gt;&gt;&gt; print('abcd\b')  
  abcd
  &gt;&gt;&gt; print('abcd\b ') 
  abc
  </code></pre>
