Example Output The following output is an example of how your program should respond to the commands. The text in bold is the user-typed input. >>> StudentManager() $ AddStudent John, Doe, 3.7, 32 $ AddStudent Jean, Davis, 3.8, 24 $ AddStudent Aaron, Johnson, 3.6, 16 $ AddStudent John, Schwartzmann, 3.9, 28 $ PrintRoster John, Doe, 3.7, 32 Jean, Davis, 3.8, 24 Aaron, Johnson, 3.6, 16 John, Schwartzmann, 3.9, 28 $ SortRoster Name Aaron, Johnson, 3.6, 16 Jean, Davis, 3.8, 24 John, Doe, 3.7, 32 John, Schwartzmann, 3.9, 28 $ SortRoster GPA John, Schwartzmann, 3.9, 28 Jean, Davis, 3.8, 24 John, Doe, 3.7, 32 Aaron, Johnson, 3.6, 16 $ SortRoster Units John, Doe, 3.7, 32 John, Schwartzmann, 3.9 ,28 Jean, Davis, 3.8, 24 Aaron, Johnson, 3.6, 16 $ DeleteStudent Julia, Taylor Error!

The namedtuple must have 4 fields: First name of the student, last name of the student, their GPA and their number of passed units. ● Your program must maintain a list called StudentRoster which contains all of the student namedtuples which are currently in the manager. ● The AddStudent command must add a namedtuple to the StudentRoster, and DeleteStudent must remove a namedtuple from the StudentRoster. ● The commands specified above and the arguments are case-sensitive. ● If the user mistypes the command or enters a command which is not valid, your program should not crash. Instead your program should ignore that command without changing the state of the student roster and instead print a new prompt to the user. ● Each function that you define must have a docstring explaining briefly what the purpose of that function is. 4. SortRoster: This command allows you to sort the list of students. Thecommand takes in only one additional argument. This argument can be"Name" or "GPA" or "Units". If the argument is "Name", your programmust sort this list of students alphabetically according to first name, andusing second name as the sort key if the first names are the same. If theargument is "GPA", then your program must sort this list of students bydecreasing order of their GPA. If the argument is "Units", then yourprogram must sort the list of students by decreasing order of the numberof passed units of the students. Finally, after sorting, your programshould print out the sorted list of students in the same format as thecommand PrintRoster.5. FindByFName: This command allows the user to look up students bytheir first name. This command takes in 1 argument, the first name of thestudent the user is trying to search. If the student is in the manager, thestudent information must be printed in a single line with items ofinformation separated by commas. Additionally, if there are multiplestudents with the same first name, the command should print informationfor all students with the matching first name.6. FindByLName: This command allows the user to look up students bytheir last name. This command takes in 1 argument, the last name of thestudent the user is trying to search. If the student is in the manager, thestudent information must be printed in a single line with items ofinformation separated by commas. Additionally, if there are multiplestudents with the same last name, the command should print informationfor all students with the matching last name.7. GetAverage: This command allows the user to get the average of theGPA or the number of passed units of all students. It takes in 1argument, "GPA" or "Units". If the argument is "GPA", your programshould calculate the average of the students' GPA weighted with thenumber of passed units of all students added to the student managerand then print this number. If the argument is "Units", your programshould calculate the average number of passed units of all studentsadded to the student manager and then print this number.8. Quit: This command terminates the program. For this assignment, you will implement a Student Manager for CS department.This program will allow the user to store information about students in CS department,their GPA and number of Passed Units, and allow them to search, edit or sort theinformation. Your program should be a function called Student Manager() that takesno arguments and returns no values.The Student Manager should be capable of accepting commands from the userand responding to those commands. Your function must print out a prompt to indicatethat the user can enter a command. The prompt should be a '$' character. At theprompt, the user will type a command followed by the required arguments. Yourprogram will then perform the specified action. Your program will then print the promptcharacter '$' again informing the user that they can type in a new command. Theprogram will continuously ask for commands and execute them until the user enters the"quit" command which will terminate your program.The following commands must be supported:1. AddStudent: This command will allow the user to add a student to thestudent manager. It takes 4 arguments: first name of the student, lastname of the student, GPA (0-4) of the student, and number of passedunits (0-100) of the student. These 4 arguments are separated bycommas. This command creates a new student and records theirinformation in the Student Manager. The students are maintained inorder based on when they are entered, so a newly entered student isalways added at the end of the ordering. The ordering can only bechanged using the SortRoster command described below.2. DeleteStudent: This command allows the user to remove a student fromthe Student Manager. This command takes 2 arguments, the first name ofthe student and their last name. These arguments are again separated bycommas. This command must print an error message if the student hasnot already been added to the student manager. On success, it printsnothing.3. PrintRoster: This command prints the details of all the students that arecurrently added to the Student Manager. This command takes in noadditional arguments. Your program should print information of onestudent per line, each item of information separated by commas.Student information should be printed in the order maintained by the StudentManager. Information about each student should be printed on a line in thefollowing order: first name, last name, GPA and number of passed units.
