Here, the app name will be added into the duplicate_apps list. My questions is that for example. If there are 5 rows of Instagram’s data. Will “Instagram” be added 4 times in duplicateapps?
Yep it would! Based on this code, it could potentially append multiple app names with the same name to the duplicate apps list. Might be more helpful to create a dictionary to get the unique number of duplicated apps, and how many times each was duplicated.
