Print multiple input entries as one display in Python-CodePudding

I wrote this code in Visual Studio Code and run this in the Terminal, and I'm able to input one entry for the list, after I input the first entry, it displays the data but it won't let me input more than one entry at a time without having to run the file in the Terminal again to input another entry. I'm trying to print the three entries once, altogether, after I input the three entries. Any advice/tips/tricks?

# This imports the sys module.

# This Retail Item class holds data about products.
class RetailItem:

    # __init__ method initializes the attributes.
    def __init__(self, description, units, price):
        self.__item_description = description
        self.__units_in_inventory = units
        self.__price = price

    # The set_item_description method gets the item type.
    def set_item_description(self, description):
        self.__item_description = description

    # The set_units_in_inventory method gets number of items available.
    def set_units_in_inventory(self, units):

    def set_price(self, price):
        self.__price = price

The line return item_list should be outside the for loop. Refer the below code:

def make_list():
    # Create an empty list.
    item_list = []
    # Add three item to the list.
    print('Enter data for three items: ')
    for count in range(1, 4):
        # Get item data.
        print('Item number '   str(count)   ':')
        item = input('Enter description of item: ')
        units = float(input('Enter number of units in inventory: '))
        price = float(input('Enter price per item: '))
        print()

        # Creat new RetailItem and assign items variable.
        items = RetailItem(item, units, price)
        # Add items to list.
        item_list.append(items)

    return item_list
