Given an input string of numbers (comma separated), write every number into a new line in a file named output.txt (without the commas). Sample Input 1,2,3 Sample Output (File output.txt) 1 2 3

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

Python programming help I need help of question 1 to read a file from persons.txt Write a program that takes a person’s details (name, age and a city), and writes to a file (persons.txt) using a loop repeatedly. You should write three person’s to the file. The program terminates on entering any key by the user, except on (Y or y) key. Sample output of the first run of the program is shown below: Enter name: JohnEnter age: 20Enter city: SydneyData saved: John 20 SydneyPress (Y or y) to add another person, or any key to exit Question 1) Write a program that read a file (persons.txt) from previous question given on the top of this question, and shows all the records/lines from the file as a nicely formatted report with a header as shown: Name Age City +---------------------+--------------------+--------------

python file by using read write append delete in same programing file

Language Python 3

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]

Write the following in C++

use c++ programing language. Read two integer number from an input file called input.txt, then add these two numbers , store it in a variable called TOTAL, find the difference of the two numbers , store it in Difference, find product to the two numbers , store it in a variable called Multiply, fine quotient of the two number call it Division, find modular division of them and store it in a variable called MUD.

Problem A straight line can be defined by a pair of points p1(x1, yı) and p2(x2, y2). The slope m of a line is defined as follow: У2 — У1 m = X2 - X1 Your program reads the points from a text file called 'points.txt’ which contains the coordinates of unknown number of pairs of points as shown in Figure 1. Each line contains four values x1, y1, x2, y2, where x1, yl are the coordinates of the first point and x2, y2 are the coordinates of the second point. 10 -2 7.5 -3.2 4 15.5 -4.6 21 -2 Зр 12.5 6. 2 5 -3 -6 10 3 10 15 Figure 1. Input file contains unknown number of point pairs Use Spider, to create the following files: (i) The input file 'points.txt' shown in Figure 1. Your Python program that reads from the input file 'points.txt', the coordinates of unknown number of pairs of points, computes the corresponding slopes then prints the results on the screen as shown in Figure 2.
