I want to print out a dictionary’s contents after the user inputs ctrl-d, and while the program handles the exception for the EOFError, it doesn’t carry out the code inside the exception.

my code is:

grocery_list = {}
while True:
    try:
        item = input("")
        for product in grocery_list:
            if item.strip().lower() == product:
                grocery_list += 1
            else:
                grocery_list[item.strip().lower()] = 1
    except EOFError:
        for product in grocery_list:
            print(f"{grocery_list} {product.upper()}")
        exit()

this is the code i particularly need executed

        for product in grocery_list:
            print(f"{grocery_list} {product.upper()}")

i expected something like:

1 APPLE
2 BANANA
1 SUGAR

once the user inputs ctrl-d if the user entered apple once, banana twice, and sugar once prior.

but upon hitting ctrl-d the program just ends

strangely enough, when i just print within the exception

    except EOFError:
        print("x")
        exit()

it does carry out and prints

x

could anyone explain?
