title: How to delete tabs in pycharm
body: <p>Im refactoring the code and want to delete tabs in almost hundred of line. It's python. To illustrate what I want to do here is initial code: </p>
  
  <pre><code>def func():
      a = x
      b = z
      f(x)
      # lines of code ...
  </code></pre>
  
  <p>Here I want to get this:</p>
  
  <pre><code>a = x
  b = z
  f(x) 
  #lines of code without tabs
  </code></pre>
  
  <p>Is it possible to do it in pycharm cause manually it takes a lot of time?</p>
