Answer 1

You need to follow the compilers messages and fix things one by one.

1. Instead of if add_choice in == '0': you should write if add_choice == '0':
2. else should be at the end, after other elifs
3. On line 26 you issue a continue command, but there is no loop to be continued. Put a loop around your menu.
4. inventory is not defined. It is not clear if you'd want to use the ShoppingCart or a simple list here, but neither has add_stocks(), make_sale() or view_inventory() functions. I belive you have some unfinished code here. You should also put any declaration, such as your ShoppingCart at the beginning of the file, before you start your code, so the compiler is aware of these type declarations.

Good luck!
