Question 1: use python
An instructor teaches a class in which each student takes three exams. The instructor would like to store this information in a file named grades.csv for later use. Write code that enables an instructor to enter each student’s first name and last name as strings and the student’s three exam grades as integers. Display the data in tabular format, including an additional column showing each student’s average to the right of that student’s three exam grades and an additional row showing the class average on each exam below that exam’s column.
This assignment is in Python. My code is at the bottom.
12.11 LAB: Course Grade
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.
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.
