Write a function MedianWithoutHL(ScoreList) that takes an unsorted list of n numbers as a parameter, discards the highest and the lowest numbers and return the median. You can assume the number of items in the list is between 0.0 and 9.9. To find the median from a list of items, you have tosort the list and find out the value of the item in the middle.Note: If the list has an odd number of items, the median is the value of the middle item. If the list has an even number of items, the median is the average of the two middle items.Sample Run #1:scoreList1 = [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]print("The Original ScoreList: ", scoreList1)print(MedianWithoutHL(scoreList1))Output of Sample Run #1:The Original ScoreList: [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]The List after sorting: [5.0, 6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0, 9.5]Without the High & Low: [6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0]7.75
(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

You are tasked with helping write part of an exciting new word-guessing game, “Durdle”. The game is one in which a player attempts to guess a five-letter word in successive guesses. In this problem and the next one, we will build an implementation of this word-guessing game. First, to support this game, we will write a function named durdle_match(guess, target) that takes in two strings - a player’s guess, and the target word that the player is attempting to guess. Each of the given words is five letters long. This function should return a five-letter string consisting of the letters B, G, and Y that has a meaning associated with the guess as follows: B: This letter in the guess does not appear in the target string Y: This letter in the guess appears in the target string in another location G: This letter in the guess appears in the same location in the target string

Your task is to implement a variation of the classic word game Hangman, which involves players guessing the letters in a word chosen at random with a finite number of guesses. While there are alternate versions such as category Hangman and Wheel of Fortune, which involve players guessing idioms, places, names and so on, we will be sticking with the traditional version. Requirements:You will implement a function called main that allows users to play an interactive hangman game against the computer. The computer should pick a word, and players should then try to guess letters in the word until they win or run out of guesses.Here is the overarching behaviour we expect:1. The program should load a list of available words from the text file provided. Note that the file you have been given contains words in lowercase.2. The computer should then select a word at random from the list at random.3. The user is given a certain number of guesses at the beginning.4. The game is interactive; the…

A supermarket wants to reward its best customer of each day, showing the customer’s name on a screen in the supermarket. For that purpose, the customer’s purchase amount is stored in a list and the customer’s name is stored in a corresponding list. Implement a function nameOfBestCustomer that returns the name of the customer with the largest sale. def nameOfBestCustomer(sales, customers) Write a program that prompts the cashier to enter all prices and names, adds them to two lists, calls the function that you implemented, and displays the result. Use a price of 0 as a sentinel. Make sure that you use functions in your solution, including a main function.

Please answer it in Python Write a palindrome function that takes a word as an argument and returns a Boolean indicating whether the word is a palindrome. A palindrome is a word that remains the same when read from right to left instead of the usual order from left to right. Example: palindrome('here') is True but palindrome('go') is False. Write a function word_allows taking as an argument a word and a list of forbidden words, and returning True if the word is allowed, and False if the word is prohibited. Example: word_allows('fric', ['sous', 'fric', 'thune', 'ble']) is False word_allows('silver', ['sous', 'fric', 'thune', 'ble']) is true
