title: Creating new column with ranges based on existing column
body: <p>I have one column with different values. I would like to make a new column that will group those values into ranges (eg. 0-5, 5-10, 10-20, etc.) How should I do it using pandas library?</p>
  <pre class="lang-py prettyprint-override"><code>df['price_group']
