USING PYTHON PROGRAMMING AND WHILE LOOPS(DO NOT USE FOR LOOPS)

Write a program that prompts the

user for the number of tests they

ve taken

,

and then asks for their grade for each test

.

For each test, ask the user

(in this exact order),

I

f

extra credit was allowed

(

yes

or

no

)

on the test.

W

hat their grade was

for the test

.

T

he program must then check the

validity

of the grade, and re

-

prompt if the

entered grade is invalid.

(The program should

not

re

-

prompt

about extra

credit,

only for a new grade

see

sample output for an example.)

I

f extra credit is

not

allowed, the grad

e must be between 0 and 100

If extra credit i

s allowed, the grade must be

0

or higher

Once the user has entered

t

he

information

about all of the

test

s

extra credit

status (

allowed or not), and a valid

s

core

for

e

ach

test

, the program should

print out the highest earned grade before exiting.

The program can assume that the number of tests will be at least one.

Y

ou are

not

requi

red to use a list for this part

of the homework,

but using one

may make certain aspects easier

.

(HINT: Think carefully about what your conditionals should look like. If

necessary, draw a truth table to help figure out what different inputs will do.

Using a Boolean flag will also likel

y make this easier.)
