Write a function called find_duplicates which accepts one list as a parameter. 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']…
4 ete t of With the following lists: list1 = [x + y for x in ['a', 'b', 'c'] for y in ['1', '2', '3']] list2 = [[x + y for x in ['a', 'b', 'c']] for y in ['1', '2', '3']] which option is true? Select one: A. len(list1)> len(list2) B. 'a1' is an element (or subelement) for list1 whereas '1a' is for list2 C. list1 and list2 will error because numbers and letters cannot be added. D. Both A and B are true.
What does the following error message normally mean? IndexError: list index out of range Select one: а. This error normally indicates that you have tried to access an element of a list that doesn't exist. O b. This error normally means that you have used the range() function incorrectly. С. This error normally means that you have used a list where you should have used a tuple. d. This error normally means that you used too many lines of code in your program.

For 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:BMWFordVolvo

1. Create/Make grades.py to do the following: a) Create an empty list named grades. b) Add the following grades one at a time to grades. 92, 51, 83, 37, 72 Output Example: c) Compute the total of these grades using the index to reference each number in grades. [92, 51, 83, 37, 72] Average: 67.00 d) Compute the average of these grades using the len method. Median: 83 e) Print the average with a precision of two decimal places. [92, 83, 72] Average: 82.33 f) Compute the location of the median grade using the len method. g) Print the median grade using index syntax. h) Remove all failing grades (lower than 60) one at time from the list. i) Print the updated list of grades. i) Print the updated average. Average = the sum of all elements divided by the number of elements Median = the middle element in a list of elements
Help make a C++ program that:1. Queries the user for the name of a file of text.2. Opens the file, and maintains two lists: one list for words beginning with the letter"D" or "d", and a second list for words beginning with any other letter. Each listmust maintain words in alphabetical order.3. Each node in the list must contain the word and the number of times that the word appears.4. Display (a screen at a time) each of the lists showing the alphabetized list of words and thenumber of times that each appears. Please have the main function as the first function in the program. Please make the least amount of functions as possible. Like for the file input have the file error thing in the same function. And please add comments throughout the code.
Part 5. Operator Overload: add Next, you will add the ability to use the addition operator (+) in conjunction with Simpy objects and floats. You will implement add such that the left-hand side operand of an addition expression can be either a simpy object or a float value using a Union type. The add_method should return a new Simpy object and should not mutate the object the method is called on. When the right-hand side of an addition expression is also a simpy object, you should assert that both objects' values attributes have equal lengths. Then, you should produce a new simpy object where each item in its values attribute corresponds to the items of the original Simpy objects at the same index added together. For example: a = Simpy([1.0, 1.0, 1.0]) b = Simpy([2.0, 3.0, 4.0]) c = a + b print(c) # Output: Simpy([3.0, 4.0, 5.0]) When the right-hand side of an addition expression is a float value, you should produce a new simpy object where each item corresponds to the item at the same…
