Select problem below. Your post must include: The problem statement. A description of your solution highlighting the use of the split(), join(), lists and the different list operations involved in solving the problems. Include line numbers from your program dont use JAVA Make Username. Create a program that reads a full name as a single string, and and uses the split creates a username with the following rules: The first character of the username is the first character of the first name. The second character of the username is the first letter of the middle name, if one was provided. The rest of the characters will be a prefix of the last name, long enough to meet the length requirement. The username can have up to 8 characters only, and in lowercase. Here is a sample execution:
Bubble Sort HouseholdSize.py 2 HouseholdSize.py - This program uses a bubble sort to arrange household sizes Summary in descending order and then prints the mean and median 3 4 household size. In this lab, you will complete a Python program that uses a list to store data for the village of 5 Input: Interactive. Marengo. 6 Output: Mean and median household size. 8 The village of Marengo conducted a census and collected records that contain household 9 # Initialize variables. 10 householdSizes = [] # Array used to store household sizes. 11 numSizes = 0 data, including the number of occupants in each household. The exact number of household records has not yet been determined, but you know that Marengo has fewer than 300 households. 12 total = 0.0 13 mean = 0.0 The program is described in Chapter 8, Exercise 5, in Programming Logic and Design. The 14 median = 0.0 15 program should allow the user to enter each household size and determine the mean and 16 # Input household size 17…

28. You are given a name arranged in bibliography (reverse) format. This line of names is then read and stored in a list so that the first element is the last name, the middle element is a comma and the last element is the first name (Assuming: the author's name only consists of 2 words). You are asked to rewrite the name in the standard format: First name + Last name. Which of the following program code fits the task? Sample Input: Putro , Hanson Sample Output : Hanson Putro A name - input ().split () print (name (1] +" +name (2) } name - input (). split () print (name (1] +" tname [0]) B C name - input ().split () print (name (2] +" "+name (0] ) name - input().split () print (name (0] +" "+name (1) ) D

python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.
Python
PYTHON Complete the function below, which takes two arguments: data: a list of tweets search_words: a list of search phrases The function should, for each tweet in data, check whether that tweet uses any of the words in the list search_words. If it does, we keep the tweet. If it does not, we ignore the tweet. data = ['ZOOM earnings for Q1 are up 5%', 'Subscriptions at ZOOM have risen to all-time highs, boosting sales', "Got a new Mazda, ZOOM ZOOM Y'ALL!", 'I hate getting up at 8am FOR A STUPID ZOOM MEETING', 'ZOOM execs hint at a decline in earnings following a capital expansion program'] Hint: Consider the example_function below. It takes a list of numbers in numbers and keeps only those that appear in search_numbers. def example_function(numbers, search_numbers): keep = [] for number in numbers: if number in search_numbers(): keep.append(number) return keep def search_words(data, search_words):
