first_name = input ("Enter first name: ")
last_name = input ("Enter last name:")
student_id = int(input("Enter your ID"))
gpa = float(input ("Enter your GPA: "))
student1 = {}
student1["first_name"] = first_name
student1["last_name"] = last_name
student1["student_id"] = student_id
student1["gpa"] = gpa
//Repeat same code for student2 and student3
class_list = {"student1": {"first_name":"joy","last_name":"Son","student_id":"1","gpa":"3.5"},
#Fill in for student 2 and 3}
#To remove GPA for all students
del class_list["student1"]["gpa"]
del class_list["student2"]["gpa"]
del class_list["student3"]["gpa"]
print(class_list)
