- Program Unit Score Calculator Console App Write a Python Console Application program that allows the user to enter the marks for different assessments in a unit, and computes the total mark and grade for the unit. Here is the program logic specification: There are six assessment activities Quiz1, Quiz2, Quiz3, Quiz4, Lab Journal, Major Assignment and Final Exam. The four quizzes are worth 5 marks each, the Lab Journal is worth 10 marks, the Major Assignment is worth 30 marks and the Final Exam is worth 40 marks. The algorithm for computing the total mark for the unit is: Total Mark = Quiz1+Quiz2+Quiz3+Quiz4+Major Assignment+ Lab Journal + Final Exam The following screenshot shows a successful test run:arrow_forwardPART I: Functions – Math Test Write the Flowchart and Python code for the following programming problem based on the pseudocode below. Write a program that will allow a student to enter their name and then ask them to solve 10 mathematical equations. The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. The program should then display whether the answer was right or wrong, and accumulate the correct values. After the 10 questions are asked, calculate the average correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name. A function that gets two random numbers, anywhere from 1 to 500. A function that displays the equation and asks the user to enter their answer.
