WebJun 24, 2024 · These are built-in functions of python, they are used for working with iterables. Basically iter () calls the __iter__ () method on the iris_loader which returns an iterator. next () then calls the __next__ () method on that iterator to get the first iteration. Running next () again will get the second item of the iterator, etc.
