Implement packing/unpacking in an object

by

You can unpack any Iterable. This means you need to implement the __iter__ method, and return an iterator. In your case, this could simply be:

def __iter__(self):
    return iter((self.name, self.age, self.gender))

Alternatively you could make your class an Iterator, then __iter__ would return self and you’d need to implement __next__; this is more work, and probably not worth the effort.

For more information see What exactly are Python’s iterator, iterable, and iteration protocols?

Per the question I linked above, you could also implement an iterable with __getitem__:

def __getitem__(self, index):
    return (self.name, self.age, self.gender)[index]
