for item in shopping_list():
The parentheses after the name mean "call this function", but "shopping_list" is a list object (and therefore not callable).
Those parentheses should just be removed.

Here's your list:
1. apples
----------
Where should I add grapes?
Press ENTER to add to the end on the list

Traceback (most recent call last):
File "shopping_list.py", line 68, in <module>
add_to_list(new_item)
File "shopping_list.py", line 36, in add_to_list
shopping_list.insert(position-1, item)
TypeError: unsupported operand type(s) for -: 'str' and 'int'

231,269 PointsTry formatting your code so the spacing shows up (in Python, indentation is critical).
Use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area.
Or watch this video on code formatting.
