Question

Create a python application that inputs, processes and stores student data.

Specifications: 1. Your application should be able to accept Student data from the user and add the information in a file type of your choice.

2. your application is a menu driven and allow the user to choose from the following menu

Menu: 1 – Add students to file

2 – print all the student information

3 – print specific student information using studentID

4 – Exit the program

2. Student Data should include the following • StudentID • FirstName • LastName • Major • Phone • GPA • Date of Birth

Example: C777777 James Bond CSAT 416-222-2222 3.88 October 15th, 1970

3. Your application should provide the functionality to display the student data as needed using student number key

4. Your application should calculate the average gpa of all the students and show the total gpa of the class along with the displayed student in previous step.

Answer 1

CODE:

#function to print the menu
def printMenu():
print('\n1. Add students to file')
print('2. Print all students information')
print('3. Print student information using studentId')
print('4. Exit program')
#function to add a student to the passed student dictionary
def addStudents(studentDict):
#asking the user of the inputs
iD = input('Enter the student id: ')

tempDict['fName'] = input('Enter the first name of the student: ')
tempDict['lName'] = input('Enter the last name of the student: ')
tempDict['major'] = input('Enter the major: ')
tempDict['phone'] = input('Enter the phone number: ')
tempDict['gpa'] = float(input('Enter the gpa: '))
