This project focuses on analyzing a publicly available dataset containing information about some infamous breaches that have occurred in the past.

open_file(message) -> fp
this function taken in a prompt message (string) and returns a file pointer. you likely have a copy from a previous project. it repeatedly prompts for a file until one is successfully opened. it should have a try-except statement. by default (when the user does not provide a filename), this function opens the file ‘breachdata. csv’. important: remember to open the file with the correct encoding as shown below.

fp = open(filename, encoding='utf8')

build_dict(reader) -> dictionary
this function accepts a csv reader as input and returns the required dictionary. it iterates over the csv reader and with each iteration, extracts the needed data and remove any extra whitespaces. you need to skip the header line before start reading the data:

next(reader, none)
the data to be extracted is:

entity - index 0 (string)
records lost - index 2 (int)
year - index 3 (int)
story - index 4 (string)
sector – index 5 (string)
method - index 6 (string)
news sources - index 11 (list of strings)
