Method_Assignment.py

"""
Your job is to add three methods to the existing program:

1. A method print_students_data that prints the name of each one of the students in the dictionary, their age, and the classes they are taking, one student per line.

A sample output would be:

"Student: Gino who is 15 years old and is taking ['Piano', 'Guitar']"
"Student: Talina who is 28 years old and is taking ['Cello']"
"Student: Eric who is 12 years old and is taking ['Singing']"
2. A method print_student that prints the string shown above with the name, age, and classes of a student. It should take the name of the student as an argument and print only the data of that particular student. (Tip: you might consider using this method in the print_students_data  method to avoid repetition).

3. A method add_student  that adds a student to the existing students dictionary. The key used to add the student to the dictionary should be the name of the student and the value should be a list with the age, phone number, and classes that the student is taking. The method should take the name of the student as a parameter and a list with the data associated with that name as another parameter.

------------------------------

After adding these methods, you should create an instance of MusicSchool with 8 working hours, and 15000 as the initial revenue. Then, call each method through that instance like this:

<instance>.print_students_data()
<instance>.print_student("Gino")
<instance>.add_student("Jack", [60, "562-234-234", ["Piano"]])
Note: remember that students is a class attribute. You will need to use a particular syntax to access it in your methods.

------------------------------

Challenge: Right now, the existing program does not store the data in a file, so new student records are lost when the program ends. Could you make this program save the students' information to a .txt file using methods? This is not required to submit the assignment, but it's an interesting program that you might enjoy working on.
