- 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.arrow_forwardWrite 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…arrow_forwardWrite a program in Python 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 grades of the students into a text file named…arrow_forward
- consider a program that reads data from a text file called: "klingon-english.txt" (shown below). How would one construct such a program with the following conditions: 1. Ask the user to choose a Klingon consonant they want to practice with. Ask again if the user’s answer is not a valid Klingon consonant, until the user enters a valid consonant. 2. Find a Klingon word that starts with the chosen consonant (the text file contains only one word that starts with any given consonant, so you don’t need to use the random library) 3. Ask the user to translate the chosen word into Klingon 4. Print "Correct" if the user’s answer is correct 5. Print "Sorry, you’re wrong!" if the user’s answer is wrong 6. Print The correct answer is ... if all three user’s answers are wrong You will also factor in this version: 7. If the answer is incorrect, show the first hint: the first and last characters of the correct Klingon word. When showing a hint, replace all other characters with a star (*) 8. If the…arrow_forwardWrite a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file. See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.arrow_forwardFor this program, assume you have an input file with several lines of text. Each line has a student's last name, followed by a space and then 4 numbers which represent his/her grades. Your program should read this input file and produce an output file with the same number of lines, each line showing the last name and the average of the student's scores. "grades.txt" is the file your program should read. "badformat.txt" is an example of a file that your program can't read, so a clear error message should be generated, as shown in the sample output. Your program must catch all exceptions. Your main method must NOT have a "throws" clause - it must catch all exceptions and dea' with them appropriately. Other methods may throw exceptions, as long as the main method catches them. I don't expect you to examine any filenames to make sure they're valid. Instead, you should use the filename the user gives you and try to open a file by that name. That will throw an exception if the filename is…arrow_forward
- 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: 75.75arrow_forwardWrite 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…arrow_forwardWrite a program that reads a student's name followed by five test scores. The program should output the student's name, the five test scores, and the average test score. Output the average test score with two decimal places. The data to be read is stored in a file called test.txt. The output should be stored in a file called testavg.txt. test.txt: A file containing the student names and the five test scores for every student.

- 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.)arrow_forwardWrite a program that will read in a file of student academic credit data and create a list of students on academic warning. The list of students on warning will be written to a file. Each line of the input file will contain the student name (a single String with no spaces), the number of semester hours earned (an integer), the total quality points earned (a double). The following shows part of a typical data file: Smith 27 83.7 Jones 21 28.35 Walker 96 182.4 Doe 60 150 The program should compute the GPA (grade point or quality point average) for each student (the total quality points divided by the number of semester hours) then write the student information to the output file if that student should be put on academic warning. A student will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other students.
