RE: NameError! shopping_list not defined - zivoni - Apr-02-2017 The error is quite clear - your dont have shopping_list defined when you call show_list(shopping_list) on line 46. Perhaps you should add return statetement with shopping_list into your shop() function and useshopping_list = shop() show_list(shopping_list)in your main function? |
