Answer 1

Answer:

#check grade and for fail

def grade(subj):

if subj > 79:

 return "A"

elif subj > 59:

 return "B"

elif subj > 39:

 return "C"

else:

 return "fail"

 

#check highest and lowest marks

def check_high_low_marks(sub,marks):

global h_temp_marks

global l_temp_marks

if marks > h_temp_marks:

 h_temp_marks = marks

 global h_sub

 h_sub = sub

if marks < l_temp_marks:

 l_temp_marks = marks

 global l_sub

 l_sub = sub

#main

h_temp_marks = 0

l_temp_marks = 100

total_marks = 0

sub_name_marks = {}#store subject and marks in dictionary

for i in range(3):

sub = input("Enter Subject Name: ")

marks = int(input("Enter Subject Marks: "))

sub_name_marks[sub] = marks#adding it to dictionary

total_marks += marks#for calculating total marks

check_high_low_marks(sub,marks)

#print total and average marks

print("Total marks =", total_marks)

print("Average marks =", total_marks/3)

print("Highest marks in", h_sub)

print("Lowest marks in", l_sub)

#checking grade and for fail

for key in sub_name_marks:

print(key, grade(sub_name_marks.get(key)))
