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:

JS Write a function named find_value that takes a list/array of whole numbers as a parameter. Your functio will need to find if the parameter contains the value 3 as an entry. Return true if the input has an entry equivalent to 3 and false if it does not.
program7.pyThis assignment requires the main function and a custom value-returning function. The value-returning function takes a list of random integers as its only argument and returns a smaller list of only the elements that end with 7. This value-returning function must use a list comprehension to create this smaller list.In the main function, code these steps in this sequence: Set random seed to 42 import randomrandom.seed(42) create an empty list that will the hold random integers. use a loop to add 50 random integers to the list. All integers should be between 200 and 250, inclusive. Duplicates are okay. sort the list in ascending order and then use another loop to display all 50 sorted integers on one line separated by spaces. print a slice showing list elements indexed 5 through 10, inclusive. print a second slice showing the final 5 elements in the sorted list. execute the custom function with the entire original list as its sole argument. report the number of elements in…

JS Write a function named list_concat that has a single parameter. This parameter will be a list/array. The parameter's entries will be strings. Your function needs to return a string. The returned string's value should be the concatention of all of the entries in the parameter with a space after each entry. Sample test cases: list_concat(["single"]) evaluates to "single list_concat(["limit", "break", "ready"]) evaluates to "limit break ready
Assume that the variable data refers to the list [5, 3, 7]. Write the expressions that perform the following tasks: a. Replace the value at position o in data with that value's negation. b. Add the value 10 to the end of data. c. Insert the value 22 at position 2 in data. d. Remove the value at position 1 in data. e. Add the values in the list newData to the end of data. f. Locate the index of the value 7 in data, safely. g. Sort the values in data.
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.

The function should be written in python language. Write a function called "zero_triples" to return all triples in a list of integers that sum to zero. You can assume the list won't contain any duplicates, and a triple should not use the same number more than once. [In]: zero_triples([1, 2, 4]) [Out]: [] [In]: zero_triples([-3, 1, 4, 2]) [Out]: [[1, 2, -3]] [In]: zero_triples([-9, 1, -3, 2, 4, 5, -4, -1]) [Out]: [[-9, 4, 5], [1, -3, 2], [-3, 4, -1], [5, -4, -1]]
