Exercise 5: Write a python program that reads from a text file whose name is provided by the user (see a sample below) blood glucose readings recorded during the last week. Each line contains a certain number of blood glucose readings followed by the patient id. Your program should then display for each patient, their id number, the number of readings, the average value of the readings followed by the patient status (Normal range: 90–120 mg/dl, Low range: less than 90 mg/dl, High otherwise). Your program should consider the following erroneous cases and display appropriate message as shown in the sample output below: • The file does not open/exist • The readings are invalid (non-integer values or negative) or missing, in which case a ValueError exception should be raised and the processing should continue. Enter input filename: patients.txt Patient Id #Readings Average Status ========== ========= ======= ====== 120 150 150 P1111 High Normal P1111 140 100 90 90 100 P2222 P2222 95 12a 100 120 P3333 P3333 Invalid readings 50 70 P4444 P4444 2 60 Low P5555 P5555 No readings Sample input file Sample output

Exercise 2:Write a Java program that allows the user to specify a file name on the command line and prints the number of characters, words, lines, average number of words per line, and average number of characters per word in that file. If the user does not specify any file name, then prompt the user for the name.
Write 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…
Write 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. The file Warning.java contains a skeleton of the…

Please do this in PYTHON PROGRAMMING Write an address book program that stores your contacts' names and their email addresses. The names and email addresses are originally stored in a file called phonebook.in, in the format:Harry P..d@hogwarts.eduHermione G..h@hogwarts.eduRon W..b@hogwarts.eduDraco M..s@hogwarts.eduSeverus S..e@hogwarts.eduAlbus D..x@hogwarts.eduYour program should read from the file, storing the names and corresponding email addresses in a dictionary as key-value pairs. Then, the program should display a menu that lets the user enter the numbers 1 through 5, each corresponding to a different menu item:1) look up an email address2) add a new name and email address3) change an email address4) delete a name and email address5) save address book and exitWhen the user enters 1, the program should prompt them for a name, and then print the corresponding email address. If there is no dictionary entry under that name, the program should print, "Sorry, no contact exists…
