Use Python to create a basic set of business requirements for the ATM.

User Account and PIN Verification

$$ When your program first runs, a user will need to enter an account number and $4-$digit PIN before

they are allowed to move forward and use the ATM.

$$ Your program should test for a valid account number$/$pin combination

o Note $-$ normally an ATM would verify the account # and pin combination against the bank's

customer database. For our purposes, just use a dummy account$/$pin combination that you have

statically assigned.

o If the proper account #$/$pin combination is not entered, the user should not advance past the

initial screen. In this instance, an informative user message should display.

o If the proper account #$/$pin combination is properly entered, the user should advance past the

initial screen and be provided a means to conduct transactions on the ATM.

After proper account # $/$ pin validation, the program needs to provide the following transaction options

$1.$ Fund Balance Inquiry

$2.$ Deposit

$3.$ Withdraw

$4.$ Exit

Assumptions$/$Business Rules

$$ The use has access to $3$ different accounts with the following initial balances:

o checking $=$ $$200$

o $1$st savings account $=$ $$1500$

o $2$nd savings account $=$ $$3000.$

$$ Deposits Processing Assumptions

o Deposits can be made on any account

o The deposit amount must be greater than $$0$ and less than or equal to $$1000$ in order to

be processed.

$$ Withdraw Processing Assumptions

o Withdraws can be processed against any account

o Withdraw amounts can only be $$20,$ $$40,$ $$60,$ $$80,$ or $$100.$

o Cannot withdraw more money than what exists in the account.

o Total withdraws from a single account cannot exceed $$300.$

o Total withdraws from ALL accounts cannot exceed $$750.$

$$ User can process multiple transactions during one "login session"

After the user processes their last transaction $($EXIT$),$ the application should display the following

information FOR EACH ACCOUNT...

$1.$ Starting Fund Balance

$2.$ Total Deposits on the account

$3.$ Total Withdraws on the account

$4.$ Ending Fund Balance

AND ALSO...

$1.$ Total dollar amount of all deposits made on all accounts

$2.$ Total dollar amount of withdraws made on all accounts
