Explanation:
This is a Python script that simulates an ATM machine, allowing users to check their account balance, withdraw money, lodge money, change their PIN, and quit the system.
The script begins by defining three lists: users, pins, and amounts, which hold the names of account holders, their corresponding PINs, and the amount of money they have in their accounts.
The script prompts the user to enter their username, which is then converted to lowercase for consistency. The script then checks whether the entered username exists in the users list, and assigns the corresponding index value to n.
If the username is found, the script then prompts the user to enter their PIN. If the entered PIN is correct, the script will proceed to the main menu, which offers the user a choice of actions to perform. If the user enters the wrong PIN more than three times, the script will exit.
In the main menu, the user can select from the following options:
- S (Statement): display the user’s account balance
- W (Withdraw): allow the user to withdraw money from their account
- L (Lodgement): allow the user to lodge money to their account
- P (Change PIN): allow the user to change their PIN
- Q (Quit): exit the system
If the user chooses to withdraw or lodge money, the script will prompt the user to enter an amount. If the amount is not a multiple of 10, the script will prompt the user to enter a different amount. If the amount is valid, the script will update the user’s account balance and display the new balance.
If the user chooses to change their PIN, the script will prompt the user to enter a new PIN. If the new PIN is not exactly four digits long, the script will prompt the user to enter a different PIN.
If the user chooses to quit the system, the script will exit.
