+ Code + Text Question no. 14: In this section you are going to use some advance web-scrapping ideas. However you don't have to code anything for that. But you have to post-process the content you get from the internet. This processing includes mapping - filtering and mapping task. This exercise is followed by a given code snippet which rewards you for your hard work. 5x3= 15 points) research (1 I hope you will learn something new here TE you feel anything confusing please do # I am not going through all the details here Import 3 from bat import Beautiful Soup LIPO 3 Laport random # Please do not feel confused with following 4 lines of code # These codes o grab all the html content from website # And we get all the image tag in a list called tags in line 11 http- ur .
