grades = {}

for i in range(number_of_students):
	# using input() can be unsafe; use raw_input() instead
	name = raw_input("Name: ")
	first_grade = int(raw_input("First grade: "))
	second_grade = int(raw_input("Second grade: "))
	grades[name] = (first_grade, second_grade)

# after running, grades will be something like
# {'Jack': (80, 90), 'Jill': (82, 98)}
