- (Data processing) Write a C++ program that reads the file created in Exercise 4, permits the user to change the hourly wage or years for any employee, and creates a new updated file.Python 9.11 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. Output the last names, first names, exam scores, and letter grades of the students into a text file named…The function file_first_chars in python takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters. NOTE: Return the function, don't print For example: Test Result print(file_first_chars("wordlist1.txt")) hsaem
- In PYTHON Write the code that will open and read the data from a file named Numbers.csv and write it to a file named justAsNumbers.csvCharacter Analysis Create a source code text file and save it as named text.txt. Write a program that reads the file's contents and determines the following: - The number of uppercase letters in the file. - The number of lowercase letters in the file. - The number of digits in the file. - The number of whitespace characters in the file. * Note: Please be sure to use the Python program when creating the program. Thanks!Question 1: Use Python (Class Average: Writing Student Records to a CSV File) 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. Use the csv module to write each record into the grades.csv file. Each record should be a single line of text in the following CSV format: firstname, lastname, exam1grade, exam2grade, exam3grade Question 2: (Class Average: Reading Student Records from a CSV File) Use the csv module to read the grades.csv file from the previous exercise (exercise 9.3). 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.
- The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.IN PYTHON Problem Statement Given a text file of Zoom users wanting to attend a meeting, filter out a list of users with the domain name @my.fltech.com or @fltech.edu. Then print the list with names (last name, first name) of those with authenticated tech email. Print one name in each new line. Note: the file name is not given by "input()". Instead, assume a file named "zoom_attendees.csv" is available that you need to open/use. Sample Input: zoom_attendees.csv Jackson,Thompson,jackson.thompson@fltech.edu Mines,mines,luke.wallace@lycos.com David,Wright,david.wright@fltech.edu Nathaniel,Butler,nathaniel.butler@aol.com Sample Output Thompson, Jackson Wright, DavidPython Question: myfile = open('sales.txt','r')Which statement is correct if the next line in a file holds the unit price of an item?
