- Debug the program debug_me.py. The program should test each of the users in the provided list. · If the list is empty, it should print “There are no users.” · If the user is “Admin,” the program should print “Hello all powerful one.” · Otherwise, for normal users, it should print “You are a normal user.” Test the program with an empty list to confirm correct operation for that case.arrow_forwardParallel Lists JumpinJive.py >- Terminal Summary 1 # JumpinJava.py - This program looks up and prints t and prices of coffee orders. 2 # Input: In this lab, you use what you have learned about parallel lists to complete a partially completed Interactive Python program. 3 # Output: Name and price of coffee orders or error if add-in is not found 4 The program should either print the name and price for a coffee add-in from the Jumpin' Jive 5 # Declare variables. Coffee Shop or it should print the message "Sorry, we do not carry that.". 6 NUM_ITEMS = 5 # Named constant 8 # Initialized list of add-ins 9 addIns = ["Cream", "Cinnamon", "Chocolate", "Amarett "Whiskey"] Read the problem description carefully before you begin. The data file provided for this lab includes the necessary input statements.

This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…arrow_forward

- I need help with the last two functions in pythonarrow_forwardFor this project you will create a program that populates a list of 8 car manufacturers. You can have theuser populate the list or you can have it predefined.(your choice)If you used a predefined list, then ask the user to add a car manufacturer to the list,Example:cars = ['Ford', 'BMW', 'Volvo']print(‘Enter a new Car Manufacturer: ’)cars.append(input())Use the len() function to acquire the length of the list.(this number is used at the end)Example:cars = ['Ford', 'BMW', 'Volvo']length = cars.len()Use the sort() function to sort the list, (Sort before it is displayed at the end)Example:cars = ['Ford', 'BMW', 'Volvo']cars.sort()and displays the contents of the list using a for loop in the following format:The 9 car manufacturers are:BMWFordVolvoarrow_forwardPYTHON!!! Write a function that will filter course grades that are stored in a list, creating and returning a new list. Your implementation must have the following rules: - The function must accept two (and only two) parameters: The first is: the maximum integer value for any grade to remain in the list (any value above the maximum will be filtered and removed from the list). The second is: the list of grades (you can assume the list contains only integer values) - The function must return a new list and not modify the existing list. - The function must use a list comprehension to filter the existing list and create the new list that is returned. - DO NOT USE THE: built-in-"filter" function.arrow_forward
