Brief

The brief for this exercise was to create a python script that would emulate the basic operation of an online bank account. The exercise is a good way to learn to create classes for efficient implementation of code.

# Create the class for the bank account
class BankAccount:
    def __init__(self, balance=0):
        self.balance = balance

    def deposit(self, amount):
        self.balance += amount
        print(f"Deposited £{amount} New balance: £{self.balance}")
    
    def withdraw(self, amount):
        if amount <= self.balance:
            self.balance -= amount
            print(f"Withdrawn: £{amount} New balance: £{self.balance}")
        else:
            print(f"Insufficient funds you loser")

    def check_balance(self):
            return self.balance     
    
# Define the function for interaction with the online banking system
def cashier():
    cashier_prompt = input(f"Cashier: Good morning. Would you like to make an account?: ")
    if cashier_prompt.lower() == "yes":
        account_name = input("Cashier: Under what name? max 5 letters: ")
        account = BankAccount()
        initial_deposit = int(input("Cashier: How much will you be depositing?: £"))
        account.deposit(initial_deposit)
        print(f"Cashier: Your account {account_name} has been created with the balance of: £{initial_deposit}")
    else:
        print("ok")
    customer = input("Is the anything else I can help you with? ")
    if customer == "yes":
        while customer != "quit":
            customer = input("Request: deposit, withdraw, balance or quit: ")
            if customer == "deposit":
                deposit = int(input("How much? "))
                account.deposit(deposit)
            elif customer == "withdraw":
                withdraw = int(input("How much? "))
                account.withdraw(withdraw)
            elif customer == "balance":
                balance = account.check_balance()
                print(f"£{balance}")
            else:
                print("Good day to you.")

cashier()    

Cashier: Good morning. Would you like to make an account?: yes
Cashier: Under what name? max 5 letters: timmy
Cashier: How much will you be depositing?: £1000
Deposited £1000 New balance: £1000
Cashier: Your account timmy has been created with the balance of: £1000
Is the anything else I can help you with? yes
Request: deposit, withdraw, balance or quit: deposit
How much? 246000
Deposited £246000 New balance: £247000
Request: deposit, withdraw, balance or quit: balance
£247000
Request: deposit, withdraw, balance or quit: quit
Good day to you.

The Bank Account Class

class BankAccount:
    def __init__(self, balance=0):
        self.balance = balance

    def deposit(self, amount):
        self.balance += amount
        print(f"Deposited £{amount} New balance: £{self.balance}")
    
    def withdraw(self, amount):
        if amount <= self.balance:
            self.balance -= amount
            print(f"Withdrawn: £{amount} New balance: £{self.balance}")
        else:
            print(f"Insufficient funds you loser")

    def check_balance(self):
            return self.balance  

The BankAccount class is the foundation of this banking simulation program. It represents a bank account with methods for basic financial operations. The class initialises an account with a balance (defaulting to 0), and provides methods to deposit money, withdraw funds (with a check for sufficient balance), and check the current balance. These methods also print informative messages about each transaction, making the program more interactive and user-friendly.

The Cashier Function

def cashier():
    cashier_prompt = input(f"Cashier: Good morning. Would you like to make an account?: ")
    if cashier_prompt.lower() == "yes":
        account_name = input("Cashier: Under what name? max 5 letters: ")
        account = BankAccount()
        initial_deposit = int(input("Cashier: How much will you be depositing?: £"))
        account.deposit(initial_deposit)
        print(f"Cashier: Your account {account_name} has been created with the balance of: £{initial_deposit}")
    else:
        print("ok")
    customer = input("Is the anything else I can help you with? ")
    if customer == "yes":
        while customer != "quit":
            customer = input("Request: deposit, withdraw, balance or quit: ")
            if customer == "deposit":
                deposit = int(input("How much? "))
                account.deposit(deposit)
            elif customer == "withdraw":
                withdraw = int(input("How much? "))
                account.withdraw(withdraw)
            elif customer == "balance":
                balance = account.check_balance()
                print(f"£{balance}")
            else:
                print("Good day to you.")

The cashier function simulates a bank teller interaction. It prompts the user to create an account, collecting necessary information like account name and initial deposit. If an account is created, it then enters a loop allowing the user to perform various banking operations (deposit, withdraw, check balance) until they choose to quit. This function effectively ties together the BankAccount class functionality with a user-friendly interface, creating an interactive banking simulation.

Finally we call the cashier function:

cashier()  

Conclusion

We created a class that is then utilised by the cashier function to provide the basic function of a banking system.
