Write a program that reads the student information from a comma separated values (csv) file. The program then creates a text file that records the course grades of the students. Each row of the file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student each separated by a comma. A sample of the student information is provided in StudentInfo.txt. 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 file from the user. • Open the text 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: o A: 90 =< x o B: 80 =< x < 90

Addition to the text book specifications, print the total of unique words in the file. Hint: Store each word as an element of a set. Note: Save text below as the file to use and name it forChap12.txt file for this assignment. Text: No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia,…6. File Analysis Write a program that reads the contents of two text files and compares them in the fol- lowing ways: • It should display a list of all the unique words contained in both files. • It should display a list of the words that appear in both files. • It should display a list of the words that appear in the first file but not the second. • It should display a list of the words that appear in the second file but not the first. • It should display a list of the words that appear in either the first or second file, but not both. Hint: Use set operations to perform these analyses.4. WarningWrite a program that will read in a file of student academic credit data and create a list of students on academic warning.

Task : Create a program that deletes a set of elements from a single word of a given string type and creates a second set of elements that consist of a single word, and also displays it on the screen.Body Mass Index Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight.
