title: group by and list out cities with maximum accidents in pandas
body: <p>I m new to pandas, I m stuck with this from a long time.. please help!
  I downloaded data from Kaggle for accidents in US. There are many columns in it like city, temperature, state, junction.. etc.
  I wanted list of cities with maximum accidents, I used <code>value_counts()</code> for it, which returns data series. Now I m trying to create one more data frame that consists of cities with more than 1500 accidents, I want to group them by cities and have selective column like temperature, weather_condition, bumps etc. output I m expecting is something like this</p>

  <p>From this it will be easy for me to analysis</p>
