this didn't work, sadly

I tried to do this:

def show_list():
    list_items = ", ".join(shopping_list.copy)
    print('Shopping List: {}'.format(list_items))

before seeing the solution, which was this:

def show_list():
    print("Here's your list:")
    for item in shopping_list:
          print(item)

,but my solution created a type error. What happened?

To call a method, you need to put parentheses (with optional arguments) after the method name. Without them you're referring to the method itself instead of the results of calling it.

    list_items = ", ".join(shopping_list.copy())
