Write а Pythоn prоgrаm thаt simulates a mystery vending machine with 5 items. The specific items dоn’t matter, only their stock quantities. The vending machine should allow the user to insert money, select an item, and complete a transaction if there is enough money and the item is in stock. After it will dispensing the item and give back the change, the machine restarts the process. The machine should handle invalid inputs gracefully. The program continues to run until the user chooses to stop. Your task is to complete the code so that the machine performs all the expected functionalities as illustrated in the finite state machine diagram below. Some functions are already provided. Given Functions:A. get_initial_stock : This function takes no inputs and returns a list of 5 values (e.g., [7, 3, 1, 5, 9]), where each value represents the inventory for an item. For example, item1 has a stock of 7, item2 has a stock of 3, and so on. The stock values are generated randomly. B. show_stock : This function takes the list of items and prints each item along with its current stock quantity. C. main : This function controls the vending machine's operation. The machine should started by initializing its stock using the given function. Then it should continue to operate until it is turned off. - if State A, prompt the user to insert money and transition to the next state as indicated in the diagram. - if State B, the machine checks if there is enough money using the check_money function. If the user has enough money, transition to the next state as shown in the diagram. - if State C, the machine (vend) dispenses the selected item, returns any change, and displays: "Your change is #". Your solution should contain the following methods:1. insert_money (State A): This function takes the current amount of money as a parameter. It first prints the current money value, then prompts the user to enter additional money. The user is allowed to enter any floating-point value between 0 and 10 (exclusive). Once a valid value is entered, the function should return the sum of the current total and the new money inserted by the user. 2. check_money (State B): This function takes two parameters: the current stock of items in the machine and the current total money in the machine. If the user does not have enough money, the function should return -1 . Otherwise, it should call show_stock to display the available options for the customer and then return 1 . 3. vend (State C): This function takes two parameters: the current stock of items in the machine and the current total money in the machine. It prompts the user to select an item. The selection options should be from 1 to 5, where each number corresponds to an item in the stock list. If the user enters an invalid number or selects an item that is out of stock, the function should prompt the user again until a valid selection is made. Once a valid selection is made, decrease the stock of the selected item by 1, print a message indicating that the selected item is dispensing, and return the remaining amount of money after the purchase. 4. main : Complete the main function by filling in the missing parts. It should initialize the stock, handle the vending machine operations using the defined methods, and continue running until the user chooses to stop. (Answer the main question in the next section by filling in the blanks) EXTRA CREDIT (+5pt):Rewrite the get_initial_stock function to return a dictionary. This dictionary should have integers as keys and the values should be a dictionary which has stock and price. For example: { 'item1': 3, 'item2': 7,}
