- 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,...arrow_forwardThe next three questions concern a program that opens a scores file provided by the user, reads it one line at a time, adds the scores as floating point numbers to a list scores, and then computes the average score.

- Write a python program that prompts the user for their favorite basketball team. It should be able to read the list of teams provided below in a file called favorite_teams.txt and check if their team is in that file. Teams in the file:JazzBullsMavericksSpursIf the team is in the file let the user know that their team is in the list of favorites. If the team is not in the file, add the team to the end of the file. Also, let the user know that their team will be added to the file.Sample Run in File:What is your favorite NBA team?

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.arrow_forward
- The Springfork Amateur Golf Club has a tournament every weekend. The club president has asked you to write a program that will read each player's name and score as keyboard input, and then save these as records in a file named golf.txt . First, the program should ask the user for the number of players. Then, it should ask the user for each name and score individually. The file golf.txt should be structured so that there is a line with the player's name, followed by their score on the next line. Here is an example: Emily 30 Mike 20 Jonathan 23 Look carefully at the following sample run of the program. In particular, notice the wording of the messages and the placement of spaces and colons. Your program's output must match this. Sample Run (User input shown in bold) Enter number of players :4↵ Enter name of player number 1 : Jimmy↵ Enter score of player number 1 : 30↵ Enter name of player number 2 : Carly↵ Enter score...arrow_forward9b_act2. Please help me answer this in python programming.arrow_forwardWrite a Python program for a simple quiz game. The questions and answers are stored in a text file named "questions.txt." Each line in the file represents a question and its corresponding options and correct answer in the format: "Question, Option1, Option2, Option3, Option4, CorrectOption." The program should load the questions from the file, present them to the user one by one, and keep track of their score. Allow the user to input their answer, and after completing the quiz, display their final score. Make sure to handle cases where "questions.txt" does not exist or has incorrect formatting. Use functions to structure your code, making it easier to understand and maintain. You can use a list or dictionary to store the questions and options. Ex: questions.txt: What is the capital of France?, Berlin, London, Paris, Madrid, 3 Who is the author of "To Kill a Mockingbird"?, Mark Twain, Harper Lee, J.K. Rowling, Ernest Hemingway, 2 What is the largest mammal on Earth?, Elephant, Blue...arrow_forward
