Question

• by python

• Question #1 Consider a 5-point quiz system. A score can be any number between 0 and 5. Using mathematical interval notation, the score is in the interval [0,5][0,5]. The interval notation (4,5](4,5] means that number 4 is not in the interval. Hence the numbers included in this interval are all real values ?x such that 4<?≤54

• The score is graded according to the following scale:

Score	Grade
(4, 5]	A
(3, 4]	B
(2, 3]	C
(1, 2]	D
[0, 1]	F

• Write a program that reads a quiz score and then prints out the corresponding grade.

• Note that your program should

  1. Prompt the user of your program using an appropriate message.
  2. Check that the input is within range (from 0 to 5). If the wrong input is given, the program should ask the user for input again until he enters a valid input.
  3. Print an output message reading: “Your grade is ” followed by the grade.

• The following are two sample runs of the program:

• Sample Run 1:
  Please enter score: -1
  Invalid score. Try again.
  Please enter score: 5.5
  Invalid score. Try again.
  Please enter score: 3.5
  Your grade is B

• Sample Run 2:
  Please enter score: 5
  Your grade is A

Answer 1

#display grades according to your marks
def display_grade():
    #takes input from the user
    grade = input("Please enter score: ")
    #1
    if(4<grade<=5):
        print("Your grade is A")
    #2
    elif(3<grade<=4):
        print("Your grade is B")
    #3
    elif(2<grade<=3):
        print("Your grade is C")
    #4
    elif(1<grade<=2):
        print("Your grade is D")
    #5
    elif(0<=grade<=1):
        print("Your grade is F")
    #repeat the function when wrong input is given
    #6
    else:
        print("Invalid score. Try again.")
        display_grade()
    return 0
    

dislpay_grade()

1. if gardes lie between 4 and 5 or equal to 5 then grade will be printed as "A".

2. if gardes lie between 3 and 4 or equal to 4 then grade will be printed as "B".

3. if gardes lie between 2 and 3 or equal to 3 then grade will be printed as "C".

4. if gardes lie between 1 and 2 or equal to 2 then grade will be printed as "D".

5. if gardes lie between 0 and 1 or equal to 0 and 1 then grade will be printed as "F".

6. if any other inputs is given then "Invalid" will be printed and the function repeat itselves.
