## exercise 3-1:
The task is to modify the given jupyter notebook. Use a local file contaning the data instead of a url. If this file doe not exist, download it from the website of Réseau Sentinelles. Note that
the download link has changed. The old one is "http://www.sentiweb.fr/datasets/incidence-PAY-3.csv". We shoudl use the new one: "https://www.sentiweb.fr/datasets/all/inc-3-PAY.csv".
