The Purchase class will also contain functions to add, remove, and view parts. The add function will append a specified part to the end of the parts list. The remove function will remove a specified part from the parts list. The view function will print out every part in the parts list on a separate line.

If the add or remove options are selected, ask the user to input the part to be added or removed, respectively. Repeat these options until the user chooses the option to exit. python
