OBJECTIVE

You will use your knowledge of functions OBJECTIVE

You will use your knowledge of functions and lists to write a Python program that allows the user to manipulate the information from a student list.

THE PROBLEM

Assuming that we have the student list below $($the information for each student is stored in the following order: ID $($integer$),$ First name $($string$),$ Last name $($string$),$ Major $($string$),$ and GPA $($float$))$:

$[[123456,$ 'Fname$1\text{'},$ 'Lname$1\text{'},$ 'Major$1\text{'},4\mathrm{.}0],[123457,$ 'Fname$2\text{'},$ 'Lname$2\text{'},$ 'Major$2\text{'},3\mathrm{.}5],[123458,$ 'Fname$3\text{'},$ 'Lname$3\text{'},$ 'Major$3\text{'},3\mathrm{.}0],[123459,$ 'Fname$4\text{'},$ 'Lname$4\text{'},$ 'Major$4\text{'},2\mathrm{.}5]]$

And, given the Python program provided in the template file, you must:

$1)$ Write the definition and implementation of the following user$-$defined functions $($in the myModule.py file$)$:

printMenu $($provided in the template file $-$ DO NOT MODIFY THIS FUNCTION$)$: This function does not receive any parameters and does not return a value. The function prints to STDOUT the following output messages:

$1.$ Add Student

$2.$ Delete Student

$3.$ Modify Student

$4.$ Print Student List

$5.$ Print Class Average

$6.$ Exit

readStudentInfo $($provided in the template file $-$ DO NOT MODIFY THIS FUNCTION$)$: This function receives the ID of the student $($integer$)$ as a parameter, reads from STDIN the student information $($first name, last name, major, and GPA$),$ and returns a list with the student's information $[$id$,$ first name, last name, major, GPA$].$

findStudentInList: This function receives the ID of the student to find in the list $($integer$)$ and the list of students $($list of lists$)$ as parameters and returns an integer value with the position of the student in the list $($if the ID is not in the list of students, the function returns $-1).$

addStudent: This function receives the ID of the student to be added $($integer$)$ and the list of students $($list of lists$)$ as parameters and returns a boolean value $($True if the new student is added to the list or False otherwise$).$ The function must request the information about the new student using the readStudentInfo function $($provided in the template file$)$ only if the student is not on the list $($you must use the findStudentInList function$).$ Finally, if the student is not on the list, the function appends the new student at the end of the list.

deleteStudent: This function receives the ID of the student to be deleted $($integer$)$ and the list of students $($list of lists$)$ as parameters and returns a boolean value $($True if the student is deleted from the list or False otherwise$).$

modifyStudent: This function receives the ID of the student to be modified $($integer$)$ and the list of students $($list of lists$)$ as parameters and returns a boolean value $($True if the student is on the list or False otherwise$).$ The function does not allow the user to change the student ID$.$ You must use the readStudentInfo function $($provided in the template file$)$ to read the new information from STDIN only if the selected student is on the list $($use the findStudentInList function$).$

printStudentList: This function receives the list with the student $($list of lists$)$ and does not return a value. Given the list of lists above, the function prints to STDOUT contents of the list of students using the following output messages:

Student # $1$: ID: $123456,$ First name: Fname$1,$ Last name: Lname$1,$ Major: Major$1,$ GPA: $4\mathrm{.}00$

Student # $2$: ID: $123457,$ First name: Fname$2,$ Last name: Lname$2,$ Major: Major$2,$ GPA: $3\mathrm{.}50$

Student # $3$: ID: $123458,$ First name: Fname$3,$ Last name: Lname$3,$ Major: Major$3,$ GPA: $3\mathrm{.}00$

Student # $4$: ID: $123459,$ First name: Fname$4,$ Last name: Lname$4,$ Major: Major$4,$ GPA: $2\mathrm{.}50$

calculateClassGPA: This function receives the list of students $($list of lists$)$ as a parameter and returns a float value with the average GPA for the students in the list.

$2)$ Modify the PA$4.$py file to call the user$-$defined functions implemented in the myModule.py file $($you only need to modify the provided code based on the comments in the template file$).$
