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

Write a program that asks the user to enter a

P

IN number

and the type of

account it is for,

and then checks

t

he PIN

for a few different requirements

before approving it as secure

and repeating the final selection to the user

.

The program follows

t

hese

rules for

P

IN numbers

:

1.

If the

PIN is for a

checking

or

debit

account, it must

a.

Be four digits

long

i.

T

his means

no leading zeros (

0678 is not valid, nor is 0003)

b.

Not

end in a

0

(zero)

2.

If the PIN is for a

savings

account, it must

a.

Be three digits

long

i.

T

his means

no leading zeros (

0

35

is not valid, nor is 00

9

)

b.

Not

be the same number repeated (333 is not valid, nor is 888, etc.)

i.

(Think carefully about how to check this one

it

s not as

difficult as it may seem!)

The program can assume that the user will enter

c

(for checking),

d

(for

debit), or

s

(for savi

ngs) as their account type.

The program must re

-

prompt the user until they provide a

PIN

/account type

combination

that satisfies all of the conditions above

.

It must also tell the

user each of the conditions they failed, and how to fix it.

If there is more than one thing wrong (

e.g.

,

not four digits, and ends in

a zero

for a

checkin

g

account)

,

the program must print out bo

th of the things that

are wrong

/

how to fix them.

For this part of the homework, you

must

have

a

n in

-

line

comment

at the top

of

each

of your programs individual

if

,

elif

, and

else

sta

tements,

explaining what is being checked

by that conditional.

(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.)
