Complete the Funnyville High School registration program where user is prompted for her full name and the program generates email id and temporary password. Sample run: generate_EmailID: This function takes two arguments: the user’s first name and last name and creates and returns the email id as a string by using these rules: The email id is all lower case. email id is of the form “last.first@fhs.edu”. e.g. For "John Doe" it will be "doe.john@fhs.edu". See sample runs above. generate_Password: This function takes two arguments: the user’s first name and last name and generates and returns a temporary password as a string by using these rules. Assume that user's first and last names have at least 2 letters. The temporary password starts with the first 2 letters of the first name, made lower case. followed by a number which is the sum of the lengths of the first and last name (For example this number will be 7 for "John Doe" since length of "John" is 4 and length of "Doe" is…
python: def shakespeare_position(role, section): """ Question 2 - Regex You are reading a Shakespeare play with your friends (as one frequently does) and are given a role. You want to know what line immediately precedes YOUR first line in a given section so that you are ready to go when it is your turn. Return this line as a string, excluding the character's name. Lines will always begin with the character's name followed by a ':' and end in a "." or a "?" Each line is separated by a single space. THIS MUST BE DONE IN ONE LINE.

What does the following python code do? f = open("sample.txt", "w") Choose all that apply. Select 2 correct answer(s) a. writes "w" to the file called sample.txt b. if the file sample.txt exists, deletes everything in it c. closes a file called sample.txt d. If the file called sample.txt exists, it writes at the bottom of the file e. opens a file called sample.txt for appending f. if the file sample.txt does not exist, it creates the file and opens it for writing g. reads the file called sample.txt starting from the top h. opens a file called sample.txt for reading
In c++ Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, th backwards End each loop with a newline. Ex If courseGrades (7, 9, 11, 10), print: 7 9 11 10 10 11 9 7 Hint Use two for loops. Second loop starts with i=NUM VALS-1. (Notes) Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades(4) See 'How to Use zyBooks Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message 32344345730rity? 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 12 13 14 const int NUM VALS-4; int courseGrades [NUM VALS]; int i; for (i = 0; i > courseGrades[1]; } y Your solution goes here Y
In Java Write a program that prints the 128-character ASCII table. It should print the tablein eight tab-separated columns. The first column contains a "Dec" heading (fordecimal number) with the numbers 0 through 31 below it. The second columncontains the ASCII characters associated with the numbers 0 through 31. The nextcolumns contain the subsequent numbers and associated ASCII characters. See thebelow sample output for details. Be aware that that output was produced by aprogram running in a console window in a Windows environment. If you runyour program in a different environment, the first 32 characters and the lastcharacter will probably be different from what’s shown below.Note that some characters display in a non-standard manner. For example, thenumber 7 corresponds to a bell sound. You can’t see a sound, but you can see thevacant spot for 7’s character in the below table. The number 8 corresponds to thebackspace character. You can’t see a backspace, but you can see how the…

C++ Nested loops: Print seats. Given numRows and numColumns, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last. Ex: numRows = 2 and numColumns = 3 prints:1A 1B 1C 2A 2B 2C #include <iostream>using namespace std; int main() { int numRows; int numColumns; int currentRow; int currentColumn; char currentColumnLetter; cin >> numRows; cin >> numColumns; /* Your solution goes here */ cout << endl; return 0;}
The next part of the program reads the file one line at a time and adds the scores, as a floating point numbers, to the list scores. scores = [] # empty list of scores for line in infile: line = line.strip() print (scores) # get score #convert to float # add to list of scores In the space below, complete the program fragment so that it prints the list of floating point scores as follows: [98.5, 97.4, 99.1, 97.2]

This is for r Regarding a for loop, which of the following is not true? The for keyword must be followed by parentheses. Following the for statement, the code to be executed is recognized by it being indented. The number of times the loop will be performed is determined by the length of the vector passed to the for keyword. The for loop can contain other for loops.
A python function opens file data.csv, reads the data from the file and spits the data into three columns, x, y and z. The data is then printed out. Function: f = open("data.csv ", "r") print('x\ty\tz'.format()) for row in f: temp = row.split(',') for cell in temp: print(cell,end='\t') print() data.csv contains: 1.2,2.1,1.1 2.3,3.2,0.6 0.7,1.9,0.1 1.8,2.5,0.3 4.6,2.7,0.9
Use C++ In a student file, there are names and scores. Find the max score and print out the names of the students with the max score. • You must get a filename as standard input. See two sample outputs on the next page. • The number of students in the file is at most 50. • You need to make two arrays (see the next page). 1. Create a string array with size 50. The array will store the names of the students. 2. Create an integer array with a size of 50. The array will store the scores of the students.
