title: Shortest way to replace parts of strings in NumPy array
body: <p>I have a NumPy string array</p>
  
  <pre><code>['HD\,315', 'HD\,318' ...]
  </code></pre>
  
  <p>I need to replace every 'HD\,' to 'HD ', i.e. I want to get new array like below</p>
  
  <pre><code> ['HD 315', 'HD 318' ...]
  </code></pre>
  
  <p>What is the SHORTEST way to solve this task in Python? Is it possible to do this without FOR loop?</p>
