The Excel workbook above contains the results to date of this year's Poohsticks tournament in the Hundred Acre Wood:

Poohsticks scores

Tigger is leading, although Pooh Bear and Roo have only played two games each.

Import the Pandas module in a new program, then read this workbook into a Pandas dataframe and show information for this using the info method:

Reading excel

Set your dataframe variable to be the results of running the pd.read_excel method of the Pandas module.


Apply the sort_values method to your dataframe to sort the rows by Poohsticks score (highest first) and within this by games played, then pick out the first 3 rows using the head function to show the current 3 leaders:

Three leaders

The leaderboard as things stand.

Apply the rename method to your dataframe, passing in a dictionary of objects where the key is the old name of each column and the value is the new name, to get this:

Renamed columns

The dataframe with its new column names.


Finally apply the agg function to your final dataframe, passing in a dictionary where the key to each item is the name of each integer column and the value is a list of statistical functions you want to apply, to get:

Summary statistics

The minimum, maximum, median and average score and number of games played.
