How can i scrap posts from a fb group using python

i want to scrap posts from a fb group and store them in a csv file using python ,how can i do that??
i have the access key .

Hi Parth;
->the simplest way i consider scrapping is using Selenium + Beautiful Soap .
this can be done without access key; but may or may not be ethical depending upon t&c of website.
->also u can check out scrapper that are made by other peoples and are open source


->storing content in csv can be done using csv writer
doing scrapping from scratch is fun so plz try scrapping from scratch first using selenium.
