Chapter 5, Problem 24PC
Using Files—Total and Average Rainfall
Write a
During the months of March–June, the total rainfall was 7.32 inches and the average monthly rainfall was 1.83 inches.
Data for the program can be found in the Rainfall. txt file located in the Chapter 5 programs folder on the book’s companion website.
Hint: After reading in the month names, you will need to read in rain amounts until the EOF is reached and count how many pieces of rain data you read in.

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…
Here are the two programs which you may choose from to do this program:
1. Using Files - Student Line Up
Modify the Student Line Up program described in Programming Challenge 14 which
states:
"A teacher has asked all of her students to line up according to their first name. For
example, in one class Amy will at the front of the line, and Yolanda will be at the end.
Write a program that prompts the user to enter the number of students in the class, then
loops to read that many names. Once all of the names have been read, it reports which
student would be at the front of the line and which one would be at the end of the line.
You may assume that no two students have the same name.
You are now to do this program reading names from a file. Names should be read in
until there is no more data to be read. I am providing for you a file named LineUp.txt
for you to use in writing this program.
I suggest that you write it first without the file and then modify to add the file.

- I am confused on how to go about writing this python program.arrow_forwardA Company wants to produce a product orders report from its product orders file. Each record on the file contains the product number of the item ordered, the product description, the number of units ordered, the retail price per unit, the freight charges per unit, and the packaging costs per unit. Your algorithm is to read the product orders file, calculate the total amount due for each product ordered and print these details on the product orders report. The amount due for each product is calculated as the product of the number of units ordered and the retail price of the unit. A discount of 10% is allowed on the amount due for all orders over GHC100.00. The freight charges and packaging costs per unit must be added to this resulting value to determine the total amount due.

The program should then display whether their answer was right or wrong, and accumulate the right values. After the 10 questions are asked, calculate the average that was correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name.
