Cannot unpack non-iterable int object
I need to use __getitem__ for all 7 arguments in my class but __getitem__ won't let me so I tried to use a tuple but I keep getting this error:
TypeError: cannot unpack non-iterable int object
What should I do?
def __getitem__(self, key):
name,author,category,Isbn_number,printing_house,date,number_of_order = key
return (self.name,self.author,self.category,self.Isbn_number,self.printing_house,self.date,self.number_of_order)

I dont get it ı mean ı understand(kinda) how getitem works but ı need to use getitem method for getting 7 arg in key cause ı want tu use a sorting function for my objects so ı need my objects to return as keys

i recommend just creating your own customgetmethod, no need to pass in any arguments to the method nor even follow the python__getitem__convention.

To make a getitem that returns the contents of each of the member variables given a key that is the same as the name of that member, you could have the class store the information in a dict and have your get_item return from that dict. E.g.:
def __init__(self, name = 'Jud', author='Jill', category='YA'):
self.elements = {'name':name,'author':author,'category':category}
def __getitem__(self, key):
return self.elements[key]
Then with an instance of the class you should be able to do things like:
aBook['name']
aBook['author']
