1. Read a list of mobile apps from a file named "Apps.txt" and store them in a Python list of dictionaries. Apps.txt: WhatsApp, Communication, 4.7, Free Instagram, Social Media, 4.8, Free Candy Crush Saga, Puzzle, 4.5, Free Google Maps, Navigation, 4.6, Free Spotify, Music, 4.9, Freemium Zoom, Business, 4.4, Freemium 1. Output all the mobile apps in your list. 2. Output all apps that are categorized as games. 3. Output all apps with a rating higher than 4.7. 4. Calculate the average user rating of all apps in your list. 5. Create a histogram of the app categories. Each element in the histogram should represent the count of apps in a specific category. 6.
