Python zdalne pobranie pliku z adresu web.

Obiecałem znajomemu pomóc chce uruchomic zadanie typu cron ze skryptem sciągającym codziennie wyniki ze strony lotto w belgii. Ale natrafiłem na cięzki temat. Zapewne zostało to zabezpieczone jakąś walidacją ?. Plik jest na stronie : https://www.loterie-nationale.be/fr/nos-jeux/lotto/resultats

trzeba zaznaczyć radiobutton "Résultats des tirages" i wcisnąć przycisk "Telecharger", wymalowałem skrypt jak ponizej, niestety zamiast pliku otrzymuje z powrotem tę stronę. Chętnie skorzystam z pomocy !!!.
