title: Pandas describe() function doesn't print anything on PyCharm
body: <p>I'm studying the crash course by google, and I'm trying to run this piece of code:</p>
  
  <pre><code>import pandas as pd
  
  city_names = pd.Series(['San Francisco', 'San Jose', 'Sacramento'])
  population = pd.Series([852469, 1015785, 485199])
  cities = pd.DataFrame({ 'City name': city_names, 'Population': population })
  cities['Area square miles'] = pd.Series([46.87, 176.53, 97.92])
  cities['Population density'] = cities['Population'] / cities['Area square 
  miles']
  cities['Is wide and has saint name'] = (cities['Area square miles'] &gt; 50) &amp; 
  cities['City name']\
      .apply(lambda name: name.startswith('San'))
  
  cities.describe()
  </code></pre>
  
  <p>If I run that on the google online notebook, it prints a table with data..if I run that on my computer using pycharm, it doesn't print anything. That's should be the output:</p>
