Python program that interactively creates a nested tuple to store the marks in three subjects for five students

Write a program that interactively creates a nested tuple to store the marks in three subjects for five students.

i.e., tuple will look somewhat like: marks((45,45,40),(35,40,38),(36,30,38),(25,27,20),(10,15,20))

tup= ()
for a in range(1,6):
    print("Enter the Marks for student ",a)
    sub1= int(input("Enter Marks for Sub 1 : "))
    sub2= int(input("Enter Marks for Sub 2 : "))
    sub3= int(input("Enter Marks for Sub 3 : "))
    tup += ( (sub1,sub2,sub3 ),)
print(tup)

Enter the Marks for student  1

Enter Marks for Sub 1 : 34

Enter Marks for Sub 2 : 23

Enter Marks for Sub 3 : 45

Enter the Marks for student  2

Enter Marks for Sub 1 : 56

Enter Marks for Sub 2 : 34

Enter Marks for Sub 3 : 45

Enter the Marks for student  3

Enter Marks for Sub 1 : 34

Enter Marks for Sub 2 : 56

Enter Marks for Sub 3 : 67

Enter the Marks for student  4

Enter Marks for Sub 1 : 34

Enter Marks for Sub 2 : 34

Enter Marks for Sub 3 : 45

Enter the Marks for student  5

Enter Marks for Sub 1 : 56

Enter Marks for Sub 2 : 67

Enter Marks for Sub 3 : 44

((34, 23, 45), (56, 34, 45), (34, 56, 67), (34, 34, 45), (56, 67, 44))
