HOMEWORK:
Part 1:
Use if-elif-else statements to create a grading system where a user inputs a percent grade (0 to 100).
if 100-90 = A
else if 89-80 = B
and so on
Part 2:
Use a while loop to print a pattern starting from 1 and ending at 46 where the difference between terms increases by 1:
1, 2, 4, 7, 11, 16, 22, 29, 37, 47
Hint: You will need 2 different variables. One of them will be the number you print and the other will be the amount you add.

#Part 1:
grade = float(input("Input a percent grade from 0 to 100 and this program will output the equivalent letter grade.: "))
if 90<=grade>=100:
print("A")
elif 80<=grade>=89:
print("B")
elif 70<=grade>=79:
print("C")
elif 60<=grade>=69:
print("D")
else:
print("F")
#Part 2:
num = 1
addNum = 1
while addNum <= 10:
print(num)
num+=addNum
addNum+=1
grade = input ("what is the grade percentage? ")
grade = int(grade)
if 90 <= grade <= 100 :
print("A")
elif 80 <= grade <= 89 :
print("B")
elif 70 <= grade <= 79 :

print("D")
else:

Solution:
Part 1:

elif p>=60:

else:

Part 2:

add=1
while num < 47:
print(num)
num=num+add
add+=1
grade = float(input("grade percentage"))
if 97<=grade<=100:
print("A+")
elif 94<=grade<=96:
