[Solved] CS1114-Homework 10-Write a function create_permutation(lst) that works in-place

Homework # 10

Question 1:a. Write a function create_permutation(lst) that works in-place. Given a list lst, this function returns a random permutation of items in lst.For example, if lst = [2, 5, 0, -1, 4, 9], one run of the function may return[5, -1, 9, 4, 0, 2], another run may return [0, -1, 2, 5, 9, 4].For more detail on permutation, check this link: https://en.wikipedia.org/wiki/Permutation

b. Write a main() function that asks user for a positive integer, n, and prints a random permutation of the integer sequence 1,2, , n.Your main() function should use the create_permutation(lst) function you created in a.For example, given n = 10, one run of your main() function may print [1, 4, 5, 2,3, 9, 8, 7, 10, 6], another run may print [4, 2, 1, 10, 8, 7, 9, 5, 3,6].

Question 2:Write a function add_list( lst1, lst2) that takes two lists of numbers of the same length and returns a list consisting of the sum of the first numbers, the sum of the second numbers, etc.For example add_list([1,2,3], [4,5,6]) should return the list [5, 7, 9] since 1+ 4 == 5, 2 + 5 == 7, etc.Your main program should prompt user for input. It should read a list of numbers, one number per line, followed by done, then another list of numbers, one per line, followed by done. If the lists have different lengths, your main program should print Lists are different lengths. If they are the same length, the main program should call add_list and print the resulting list, one number per line.Note: you may define additional helper functions in your program.

Question 3:Implement the function create_prefix_lists(lst) that will return a sequence oflists, each containing a prefix of lst. All of the lists should be collected as one big list. Forexample for [2,4,6,8,10] the function should return [[], [2], [2,4],[2,4,6], [2,4,6,8], [2,4,6,8,10]]

Question 4:a) Write a function, read_menu() that prompts the user to enter a number n, followed by n lines, each of which has the name of some food and a price. The food name and the price are separated by a : symbol.read_menu() returns a list of tuples, each of which has a string as the first component(representing a food name on the menu) and a float as the second component (representing the price).Example, when calling read_menu(), the following execution can occur:How many items are on the menu? 4Enter item in the form name-price: tomato soup:3.5Enter item in the form name-price: pea soup:3.5Enter item in the form name-price: ham sandwich:5Enter item in the form name-price: cheese sandwich:4.5

Your function should returned list: [(tomato soup, 3.50), (pea soup, 3.50), (ham sandwich, 5.00), (cheese sandwich, 4.50)]

Hint: You may use the split function with argument :For example,>>> tomato soup:3.5.split(:)[tomato soup, 3.5]

b) Write a function read_customer_order() that prompts the user to enter a sequence of items they would like to order, followed by the word done.read_customer_order() returns a list of strings, one element for each food.Example:What would you like to order?ham sandwich pea soup done

Your function should return [ham sandwich, pea soup]

c) Write a function compute_price(menu_list, order_list) that takes a list of tuples (item, price) representing the menu, and a list of strings representing the customers order and returns the sum of the prices of the items the customer ordered.For example, given the example inputs from a) and b), your function should return 8.5.

d) Write a main()function that calls the other functions to prompt the user to enter the menu, then prompts three customers to enter their orders and prints the total price for each of them (along with 8.5% tax and 15% tip).
