2. Hamza wants to create a program that asks a user whether he has seen the moon or not. If the user replies with yes,
Hamza wants to display the message 'EID MUBARAK'.
Ans. answer = input('Have you seen the moon? (yes/no) ')
if answer == 'yes':
print('EID MUBARAK')
3. Jacky has just finished his Class 9 final exams. He knows that his teachers will soon share marks scored by all students in his
class. Thereafter, the percentage will be calculated and then each student will be given grades according to the table given
below:

Percentage of Marks Grade
>=95 Outstanding
>=90 and <95 A
>=75 and <90 B
>=60 and <75 C
<60 D
He wants to write a program in Python for his friends which allows one to enter marks scored in all five subjects - English,
Hindi, Maths, Science and Social Science. The program will then calculate the percentage, assuming the maximum mark in
each subject to be 100. Thereafter, the program should display the Grade achieved by the student. Help Jacky to complete
his task.

Ans. def grade(marksEnglish, marksHindi, marksMaths, marksSc, marksSSc):
'''
Objective: To find and display grades
Input Parameters:marks in five subjects - int values
Return Value: grade
'''
if marksEnglish>=33 and marksHindi>=33 and marksMaths>=33 and marksSc>=33 and
marksSSc>=33:
#Eligible to be promoted
totalMarks = marksEnglish + marksHindi + marksMaths + marksSc + marksSSc
percent = (totalMarks/500)*100

if percent>=95:
grade = 'Outstanding'
elif percent >= 90 and percent<95:
grade = 'A'
elif percent >=75 and percent<90:
grade = 'B'
elif percent>= 60 and percent<75:
grade = 'C'
elif percent < 60:
grade = 'D'
else:
# Not eligible to be promoted
grade = 'Failed'
return grade
