title: Divide Data Frame Python
body: <p>I am pretty new user of Jupiter Notebook and struggling to find a solution of the case below :
  I am having a df with 177 rows containing Country Name and Number of Bookings ( two columns in total)<a href="https://i.stack.imgur.com/CEUVT.png" rel="nofollow noreferrer">enter image description here</a></p>
  <p>My desire is to plot as bar chart the Top 10 countries in terms of number of reservations (quantile 0.9 yields 650 bookings) along with all others merged in one 'other countries' category.
  How could I do that ?</p>
