object oriented programming in python . i want to create project of vending machine with 3 classes and asking the user at the end if he wants anything else .if yes start from the begining if no say bye . you can use this code or new one what ever easy for you and thank you.

import sys

class Item:

def __init__(self, name, price):

self.name = name

self.price = price

class VendingMachine:

def __init__(self):

self.items = [

Item("Tea", 0.50),

Item("Coffee", 1.00),

Item("Coke", 1.50),

Item("Orange Juice", 1.00)

]

self.money_inserted = 0.00

def display_items(self):

for code, item in enumerate(self.items, start=1):

print(f"[{code}] - {item.name} (${item.price:.2f})")

def insert_money(self, money):

if money <= 0.00:

raise ValueError

self.money_inserted += money

def main():

vending_machine = VendingMachine()

vending_machine.display_items()

while True:

try:

user_selection = int(input("Please enter the desired item code: "))

except ValueError:

continue

if user_selection in range(1, len(vending_machine.items)+1):

break

item = vending_machine.items[user_selection-1]

print(f"You've selected \"{item.name}\" - the price is ${item.price:.2f}")

while vending_machine.money_inserted < item.price:

print(f"You've inserted ${vending_machine.money_inserted:.2f} into the machine so far.")

while True:

try:

money_to_insert = float(input("Please enter the amount of money you'd like to insert: "))

vending_machine.insert_money(money_to_insert)

except ValueError:

continue

else:

break

print(f"Thank you! Please take your \"{item.name}\".")

print(f"The remaining change in the machine is ${vending_machine.money_inserted - item.price:.2f}.")

return 0
