title: How to stop PyCharm inserting spaces for fine alignment when reformating code?
body: <p>I'm indenting my Python code using tabs and PyCharm is very keen on doing fine alignment using spaces, while it doesn't make the code invalid I would like to know how to stop that behavior.</p>
  
  <p>Here for instance, 2 spaces were inserted before each elements except the first one to maintain the alignment with it.</p>
  
  <pre class="lang-py prettyprint-override"><code>INDEXES_TO_ILLUMINANTS = {0: "Unknown",
                            1: "DayLight",
                            2: "Fluorescent",
                            3: "Tungsten (Incandescent Light)",
                            4: "Flash",
                            9: "Fine Weather"}
  </code></pre>
