One very common problem I have seen this semester is the loss of the ability to name the type of a particular variable or function. While this is unnecessary as far as the language definition is concerned, we do need to keep up with this information in order to successfully complete programs.
Read the following class definitions, and answer the questions below.

#Purpose: Represent a Student for a gradebook class
ASSIGNMENTS = "assignment"
QUIZZES = "quizzes"
class Student:
def __init__(self, input_name):
self.name = input_name
self.grades = {}
self.grades[ASSIGNMENTS] = []
self.grades[QUIZZES] = []
def add_grade(self, grade, category):
self.grades[category].append(grade)
def compute_assignment_average(self):
assignment_sum = 0
for grade in self.grades[ASSIGNMENTS]:
assignment_sum += grade
return assignment_sum / len(self.grades[ASSIGNMENTS])
def compute_quiz_average(self):
quiz_sum = 0
for grade in self.grades[QUIZZES]:
quiz_sum += grade
return quiz_sum / len(self.grades[QUIZZES])
def compute_average(self):
return (self.compute_assignment_average() +
self.compute_quiz_average()) / 2
What are the types of the following variables, attributes, and methods?
