in python only,

please follow pseudocode for customer and account. make sure the output is coming correct thank you.

Read everything before doing anything! In this project, you will write two files: a class that represents a bank account and a program that works ike an ATM for bank accounts. The Bank Account Class In a file named account.py, create an Account class. An account object has these attributes: acct_number: the account number (an integer) name : the account holder's name pin: the account holder's PIN, which is a four- character string, since it can have leading zeros. balance : the current balance in the account, which is a float Implement these methods: _init__(self, acct_number, name, pin, balance) The constructor _str_(self) Returns a string giving the account ID, name, PIN, and balance, separated by colons. Do not use formato on the balance; you want to keep the number as accurate as possible. deposit(self, amount) Adds the given amount (a float ) to the current balance. If the amount is negative. the balance 0 7:19 0 MP @ 95% balance. If the amount is negative, the balance must not be changed; otherwise, the balance attribute is updated to reflect the deposit. This method returns the updated balance. withdraw(self, amount) Withdraws the given amount (a float) from the current balance. If the amount is negative or greater than the current balance, the balance must not be changed; otherwise, the balance attribute is updated to reflect the withdrawal. This method returns the updated balance. Note that deposit and withdraw() do not print error messages if they get incorrect input; they simply ignore it. It is up to the program that calls these functions to provide the error messages for the user of the program. The Customer Program Write a program named lastname_firstname_customer.py that provides an "ATM" interface to a set of bank accounts. Use this accounts.dat file to set up the initial set of accounts. Each line of the text file has an account ID, name, PIN, and starting balance, separated by colons. Your program must first read the account data file and build a dictionary with the account number as the key and the Account object as the value. The program will repeatedly ask for an account number (or ENTER to quit). This is equivalent to inserting an ATM card. Repeat until the account number is valid. Once you have an account number, prompt for the PIN. The PIN must have exactly four digits. (Hint: use isnumerico ) If the customer presses just ENTER, presume that the customer doesn't want to do any transactions. If the PIN is given incorrectly three times, then 7:19 0 ME @ 95% i TOMTIDEN FOR ENTERWYU TI QUIVCLICTICE inserting an ATM card. Repeat until the account number is valid. Once you have an account number, prompt for the PIN. The PIN must have exactly four digits. (Hint: use isnumerico ) If the customer presses just ENTER, presume that the customer doesn't want to do any transactions. If the PIN is given incorrectly three times, then return to the account number prompt. Once you have a valid PIN, print a message that greets the customer by name. Then repeatedly ask the customer if they want to deposit, withdraw, or finish the transactions. If the customer wishes to deposit, ask for the amount until you get a number greater than or equal to zero; then perform the transaction and display the balance. Print an appropriate message for invalid input. If the customer wishes to withdraw, ask for the amount until you get a number greater than or equal to zero and less than or equal to the current balance; then perform the transaction and display the balance. Print an appropriate message for invalid input. If the customer is finished, print a message to say goodbye to the customer, write the entire account data structure back to disk, and return to the account number prompt. (This is equivalent to giving the customer their card back), This program must print all monetary amounts preceded by a dollar sign and with two digits after the decimal point. Sample Output Here is what your program output might look like: 7:19 0 ME ON S95% Enter account number or ENTER to quit): 1234 Invalid account number Enter account number (or ENTER to quit): 1062 Enter a 4-digit PIN: 1111 Enter a 4-digit PIN: 2222 Enter a 4-digit PIN: 3333 Sorry, could not validate you as a customer.
