I’m trying to scrape usernames off of an Instagram users’ follower list. apart from username and password, what do I need to change here? Where do I mention the user name from whom I need to scrape off the follower list? Furthermore, 2 libraries are not loading up (instaloader and urllib3). Edit: The error I got when I tried running the script: ModuleNotFoundError: No module named 'urllib3'.
