In Python  Write a program that consists of (at least) two function: A function that creates and saves data in a file. The saved data represents exam grades. In the function, you will create n random numbers in the range [0,100], where n is the number of students. The function can be called as follows: createFile(filename, n) Main function, in which the user inputs the file name and the number of students, then the main calls function createFile. The main should perform validation for n (should be > 0), and the filename (should end with .txt). I will explain how to validate strings in the coming lecture. Hint: a good developer will write four functions to solve the problem.

In c++ write a code that tells a user to enter a filename and read that text file line by line.

Using Python

create a Python program that: Opens a file and reads the contents of the following file trips.txtDownload trips.txt The file contains several lines of data, with each data item separated by commas.  The data is: A trip date The amount of fuel used on the trip The number of miles traveled on the trip For each of the lines of data in the file, separate the data items and put them in appropriate variables The file contents are in the form of strings, so you must convert the numbers in the data into the proper type Create a function that calculates the fuel mileage achieved on each trip Pass the appropriate data to this function Place this function in a separate module Call the function as needed and have the function return the calculated fuel mileage Create a function that displays the following items on a single line, and place the function in the same module as the previous function. Pass the appropriate data to this function Trip data Amount of fuel used Numbers of…

Python programming language    Write a program that asks the user for a number. Write the number to a file called total.txt. Then ask the user for a second number. Write the new number on line 2 with the total for both numbers next to it separated by a comma. Then ask the user for a third number and do the same. Keep asking for numbers until the person puts in a zero to terminate the program. Close the file. Be sure to use at least 2 functions [main() and total_numbers(number, total)]. Put all inputs and outputs into the main function, with all calculations into the total_numbers function.   Give me a number: 13 Give me another number: 14 14 + 13 = 27 Give me another number: 3 3 + 27 = 30 Give me another number: 4 4 + 30 = 34 Give me another number (0 for quit): 0 Your total is 34.       Write a program that displays the lines from the total.txt file in the following output. Use a try catch phrase to check for errors. Use only one function for this portion [main()].   13 14, 27 3,…

JAVA PROGRAM   Chapter 4. Homework Assignment (read instructions carefully) Write a program that asks the user for the name of a file. The program should read all the numbers from the given file and display the total and average of all numbers in the following format (three decimal digits): Total: nnnnn.nnn Average: nnnnn.nnn Class name: FileTotalAndAverage   double_input1.txt double_input2.txt   PLEASE MODIFY THIS CODE, SO WHEN I UPLOAD IT TO HYPERGRADE IT PASSES ALL THE TEST CASES, BECAUSE WHEN I UPLOAD IT TO HYPERGRADE IT DOES NOT PASS THE TEST CASES. IT HAS TO PASS ALL THE TEST CASES. I PROVIDED THE CORRECT OUTPUT AS A SCREENSHOT AS A REFERRENCE.    import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.util.InputMismatchException;import java.util.Scanner;public class FileTotalAndAverage {    public static void main(String[] args) {        Scanner scanner = new Scanner(System.in);        String fileName;        do {…

In Python plEASE The Payroll Department keeps a list of employee information for each pay period in a text file. The format of each line of the file is the following: <last name> <hours worked> <hourly wage> Write a program that inputs a filename from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular format with the appropriate header. Each line should contain: An employee's name The hours worked The wages paid for that period. An example of the program input and output is shown below: Enter the file name: data.txt Name Hours Total Pay Lambert 34 357.00 Osborne 22 137.50 Giacometti 5 503.50
