Bank Application

This is a simple console-based bank application implemented in Python. It allows users to log in, deposit money, and transfer funds. The application uses basic file handling for recording transactions.

Code Overview

Bank Class

The Bank class encapsulates the functionality of the bank application. It has methods for logging in, depositing money, transferring money, and starting the application.

Methods

• __init__(self): Initializes the account_details dictionary to store account balances.

• log_in(self):

  • Prompts the user for a username and password.
  • Writes hardcoded account details to account_details.txt.
  • Checks if a specified directory exists.
  • Validates the password against a hardcoded value (12345) and prints a welcome message if successful or an error message otherwise.

• deposit(self):

  • Prompts the user for an account name and an amount to deposit.
  • Updates the account balance in the account_details dictionary.
  • Writes a deposit receipt to deposit_reciept.txt.

• transfer(self):

  • Prompts the user for an amount to transfer.
  • Prints a message indicating the transfer amount.
  • Writes a transfer receipt to Transfer_reciept.txt.

• start(self):

  • Displays a menu with options to log in, deposit money, transfer money, or exit the program.
  • Handles user input to call the appropriate method based on the selected option.

Usage

1. Running the Application:
   • Run the script using Python: python bank.py
   • Follow the on-screen prompts to log in, deposit money, or transfer funds.

Example

Here is a step-by-step example of how the application can be used:

1. Log In:

   • Enter a username.
   • Enter the password (12345).

2. Deposit Money:

   • Select the deposit option.
   • Enter the account name.
   • Enter the amount to deposit.

3. Transfer Money:

   • Select the transfer option.
   • Enter the amount to transfer.

4. Exit:

   • Select the exit option to close the application.

Notes

• The password for logging in is currently hardcoded as 12345.
• The directory path in the log_in method is set to r"C:\Users\User\OneDrive\Desktop\New folder (2)". You may need to update this path to a valid directory on your system.
• The application writes receipts for deposits and transfers to text files in the same directory as the script.
