Write a program to compute Letter grades for a course. The course records are in a file that will serve as the input file. Each line of the file contains a student’s last name, then one space, quiz scores, All on one line. The program should ask the instructor about the grading scheme. Based on the input grades and the grading scheme, the system will print out for the instructor the final letter grades for all students. The instructors can choose an option to save all the grades in a text file.

Write a program that reads student data from a file, compute their GPA and writes the results to a different file. 1. The user should have the option to either enter their text file that contains the student grades or use the provided text file that contains theinformation.

Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • Compute the average exam score of each student. • Assign a letter grade to each student based on the average exam score in the following scale: ◦ A: 90 =< x ◦ B: 80 =< x < 90 ◦ C: 70 =< x < 80 ◦ D: 60 =< x < 70 ◦ F: x < 60 • Output the first names, last names, exam scores, and letter…

Write a program that asks any number of students to enter their final grade and enables you to store these grades into a grades.txt plain text file. Then it reads the grades from the grades.txt file, and displays the individual grades and their count and average.
Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores, and letter grades of the…
The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form:TFFTFFTTTTFFTFTFTFTTEvery other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry:ABC54301 TFTFTFTT TFTFTFFTTFTindicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9. The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score, followed by the test grade. Assume the following grade scale:90%–100%, A; 80%–89.99%, B; 70%–79.99%, C; 60%–69.99%, D; and…
Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams Use arrays to solve the problem.
Write a program, and store it in a file called Travel Expenses.xlsm, that does the following: (a) It asks for a person’s first name and stores it in firstName; (b) it asks for a person’s last name and stores it in lastName; (c) it asks for the number of miles the person traveled on a recent trip and stores it in nMiles; (d) it asks for the average miles per gallon the person got on the trip and stores it in milesPer- Gallon; (e) it asks for the average price per gallon paid for gas on the trip and stores it in avgPrice; (f) it calculates the cost of the trip and stores it in tripCost; and (g) it displays a message such as "Bob Jones traveled 800 miles, got 31.3 miles per gallon on average, paid $3.49 per gallon on average, and paid a total of $89.20 for gas." Make sure there is an Option Explicit line at the top of the module and that you declare all of your variables appropriately.
Once the modelling has been run, the user should have the option to rerun it. Each time it is run, the output should be saved to disk with the following filename: report_s.txt, where s is a number returned by int(time. time() ) (time. time() is a function from the time module, which you will need to import). This returns the number of seconds since 1/1/70 so that each value of s will be a unique timestamp. For example, the file may look like this: report_1586386072.txt. Part 2: In addition, your program must be able to visualise the information. The user should be able to choose the year and see two-liner graphs based on monthly averages of trade volume and monthly averages of the closing value
Create a program that calculates the average test scores. Given the student’s name and five test scores, calculate the test scores. The student’s name, five test scores and the average test score is stored in the file testaverage.txt. The data is input from the file test.txt. Sample Run Input file (Contents of the file test.txt) Andrew Miller 87.50 89 65.75 37 98.5 Output file (Contents of the testaverage.txt) Student Name: Andrew Miller Test Scores: 87.50 89.00 65.75 37.00 98.50 Average test score: 75.75
Write a program that receives a filename as user input. The file is structured as multiple lines containing numbers separated by a single space.For example, this would be an acceptable file: 1 2 3 4 5 6 7 2 Your program should open this file and: print all its contents; write the median of all numbers to a new file called result.txt. IMPORTANT NOTES: the median is the element in the middle when you sort the values; the median of values (2, 1, 3) is 2, because when you sort them, you get 1, 2, 3, and 2 is the value in the middle. you can assume there will be no empty lines; there might be any arbitrary number lines in the file; there might be any arbitrary number of elements in a single line; you can assume there will always be an odd number of elements. Example 1: If input is: file1.txt and the contents of file1.txt are: 1 2 2 you should first print the content, and then write 2 to result.txt. Example 2: If input is: file2.txt and the contents of file2.txt are: 1 2 3 4 5 1 7 you…
Write a program that reads a file consisting of students' test scores in the range 0-200. It should then determine the number of students has scored in each of the following ranges:0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, and 175-200. Output the score ranges and the number of students. (Run your program with the following input data: 76, 89,150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129,149, 176, 200, 87, 35, 157, 189.)
