The objective of this problem is to show that you can write a program that reads a text file and uses string methods to
manipulate the text.
File cart.txt contains shopping cart type data from golfsmith.com representing the gifts you have purchased for your
dad for this past Fathers Day. Good for you. You have been very generous!
The first item in each row of the file is the part number, the second the quantity, the third the price and the fourth the
description.
Your program will read the file line by line and compute the total cost of all of the items in the list. You will then
display a message that looks like this, assuming the cost of each item adds up to 168.42:
Here's what your output should look like:
The total price for the awesome Fathers Day gifts you bought is $168.42.
The shopping cart can be found here: cart.txt. Right click on the link and save the file to the folder
where you have your Python files.
Your program should use a loop to read data from a text file which contains students' names and 3 exam scores. The program should calculate the exam average for each student, determine the appropriate letter grade for that exam average, and print the name, average, and letter grade. After printing all this, you need to print the count of the total number of A's, B's, C's, D's, and F's for the whole class.
The text file you need to use can be accessed using this link: scores.txt.
Copy this file to the folder where your program will reside. The text file contains a list of 30 records, and each record contains a name and that person's 3 test scores. Each field is separated by a tab character. The first 2 records looks like this:
Davis 88 92 84Wilson 98 80 73
and so on. Your program will need to open this file and read each line until the end of file. I recommend calculating a student's exam average and letter grade as you read the file, although this is not a…
Write a program that removes all the occurrences of a specified string from a text file.For example: my Aunt went to buy Medicines while Sam and I play Soccer.removes the string Sam from the file. 1) You should create a file with this paragraph. 2) removes the string "John and" from the file.

- Complete the following incomplete program (begin by copy-pasting that into a new program file). The completed program will provide a user interface to draw as many circles as the user wants only by clicking in the window. After getting the number of circles (n) to draw as input from the user through the provided interface, the program should iterate n times. In each iteration it should wait for the user to click twice and draw a circle with center at the point where the user clicked first and with radius calculated as its distance from the second point where the user clicked. It should then fill the circle with a random color. Hints: Distance between two points with coordinates x1 & y1 and x2 & y2 and can be calculated as sqrt((x1-x2)2 + (y1-y2)2 ). To generate a random color, use randint(0,255) from the random libray to generate a random number between 0 and 255 (both inclusive). Use it three times to get the r, g and b values to generate a random color from graphics import…arrow_forwardYou are required to implement a program which will read in a text file (.txt) containing words which are arranged in sentences. Your program should first ask the user for the name of the file and then count the number of individual words and characters (including numbers and punctuation) in the file. The word and character count result should be printed on the screen. Furthermore, your program should count the number of individual words starting with the letter 'A', 'B', 'C' and so on to 'Z'. Again, these statistics should be printed on the screen. Your program should display the letter that appears at the start of most words. The program must be written in C. You should illustrate the operation of your program by generating a text file containing 3 sentences from a lead news story on the day of testing.arrow_forward(a) A short description of your algorithm, where you explain the dynamic programing approach (see the sketch of the Algorithm below).

If they match number (see below), output the prize The numbers can be in any order the random numbers can be duplicates, so be careful how you count! This work in a similar way to mini-assignment number 48 - but you DO NOT have to write to a text file. Have the user enter the numbers into the text file.
