Hi Anbu23,

Thank you for your help!

Is there another way to code this program by using for? I want to learn as much as possible.
I am gonna use your code though but I want to learn as much as possible about Python.
By the way, I am a bit confused about the order of your code.

I tried this code but I got this error "SyntaxError: multiple statements found while compiling a single statement".

        
          
          
              
              items = []
print("Welcome to the Marks Calculator! ")
while True:
    studentID = int(input("Enter Student ID >> "))
    atMark = float(input("Enter Assessable Tutorial mark (/10) >> "))
    asMark = float(input("Enter Assignment mark (/100) >> "))
    exMark = float(input("Enter Exam mark (/150) >> "))
    finalGrade = int(asMark*20/100)+(exMark*70/150)+atMark
    proceed = input("Would you like to process another student’s marks?(Y/N)>> ")
    if proceed.upper() != "Y":
        items.append( [studentID, finalGrade] )
        print(items)
        print("Program has terminated, goodbye!")
break;

            

        
      

Update: I run this code on Jupyter and it worked, however, I got this result:

Welcome to the Marks Calculator!
Enter Student ID >> 20481792
Enter Assessable Tutorial mark (/10) >> 8
Enter Assignment mark (/100) >> 78
Enter Exam mark (/150) >> 78
Would you like to process another student’s marks?(Y/N)>> y
Enter Student ID >> 205876543
Enter Assessable Tutorial mark (/10) >> 6
Enter Assignment mark (/100) >> 78
Enter Exam mark (/150) >> 121
Would you like to process another student’s marks?(Y/N)>> n
[[205876543, 77.46666666666667]]
Program has terminated, goodbye!

The program just printed out the last value that were introduced.

Really close, but you use assignment to add to a dictionary.

dictionary[key] = value

        
              items = {}
print("Welcome to the Marks Calculator! ")
while True:
    studentID = int(input("Enter Student ID >> "))
    atMark = float(input("Enter Assessable Tutorial mark (/10) >> "))
    asMark = float(input("Enter Assignment mark (/100) >> "))
    exMark = float(input("Enter Exam mark (/150) >> "))
  
    finalGrade = int(asMark*20/100)+(exMark*70/150)+atMark
    items[studentID] = finalGrade # This is how you add to a dictionary
  
    proceed = input("Would you like to process another student’s marks?(Y/N)>> ")
    if proceed.upper() != "Y":
        break:
 
for studentID, finalGrade in items.items():
    print(studentID, finalGrade)
print("Program has terminated, goodbye!")

The only code inside a loop should be code you want to run over an over. Did you want to print the welcome each time a student was added? Student marks are echoed at the end of the program, so put that at the end of the program.

Hi deanhystad,

I run your code but for some reason I didn't get any output.

        
              items = {}
print("Welcome to the Marks Calculator! ")
while True :
    studentID = int(input("Enter Student ID >> "))
    atMark = float(input("Enter Assessable Tutorial mark (/10) >> "))
    asMark = float(input("Enter Assignment mark (/100) >> "))
    exMark = float(input("Enter Exam mark (/150) >> "))
 
    finalGrade = int(asMark * 20 / 100) + (exMark * 70 / 150) + atMark
    items[studentID] = finalGrade
 
    proceed = input("Would you like to process another student’s marks?(Y/N)>> ")
    if proceed.upper() != "Y":
        break;
 
        for studentID, finalGrade in items.items():
            print(studentID, finalGrade)
        print("Program has terminated, goodbye!")﻿﻿

Does it mean that the input is not being stored in the variable items?

Hi anbu23,

I run your code too, but for some reason it's not working for me.... I know that I am missing something but I cannot find the error.

        
              items = []
print("Welcome to the Marks Calculator! ")
while True:
    studentID = int(input("Enter Student ID >> "))
    atMark = float(input("Enter Assessable Tutorial mark (/10) >> "))
    asMark = float(input("Enter Assignment mark (/100) >> "))
    exMark = float(input("Enter Exam mark (/150) >> "))
 
    finalGrade = int(asMark*20/100)+(exMark*70/150)+atMark
    items.append([studentID, finalGrade])
 
    proceed = input("Would you like to process another student’s marks?(Y/N)>> ")
 
    if proceed.upper() != "Y":
 
        for studentID, finalGrade in items:
            print(studentID, finalGrade)
            print("Program has terminated, goodbye!")
            break;

As you can see below the program never stops and it just show me one result.

The statements with the same indentation belong to the same group similar to blocks created in other programming language using {}

break is part of for loop due to indentation. Hence it print first row and breaks. It should have same indention as "if".

        
              if proceed.upper() != "Y":
  
    for studentID, finalGrade in items:
        print(studentID, finalGrade)
        print("Program has terminated, goodbye!")
        break;

Same issue in your implementation of deanhystad's code
