Code Explanation

Class ATM

• __init__: Initializes the ATM with a balance of 0 and an empty transaction history.
• display_balance: Displays the current balance.
• transaction_history: Prints the transaction history. If no transactions have been made, it notifies the user.
• withdraw: Deducts the specified amount from the balance if sufficient funds are available and records the transaction. Displays the updated balance.
• deposit: Adds the specified amount to the balance and records the transaction. Displays the updated balance.
• transfer: Transfers the specified amount to another account if sufficient funds are available, records the transaction, and displays the updated balance.
• quit: Prints a goodbye message and exits the program.

Function main

• Initializes an instance of the ATM class and another target account for transfer demonstration purposes.
• Provides a menu for the user to interact with the ATM.
• Processes the user's choice and performs the corresponding action by calling the appropriate methods in the ATM class.

Usage

To run the ATM interface, simply execute the main function. The user can interact with the ATM through the console, making choices and entering amounts as needed.

Example

if __name__ == "__main__":
    main()
