Is there a way to get the item pointed at by an iterator in python without incrementing the iterator itself? For example how would I implement the following with iterators:
looking_for = iter(when_to_change_the_mode) for l in listA: do_something(looking_for.current()) if l == looking_for.current(): next(looking_for)

We use the next() function to manually iterate through all the items of an iterator.
The previous index and next index in an ArrayList can be obtained using the methods previousIndex() and nextIndex() respectively of the ListIterator interface.
Iterator in python is an object that is used to iterate over iterable objects like lists, tuples, dicts, and sets. The iterator object is initialized using the iter() method. It uses the next() method for iteration.
The next() function returns the next item in an iterator. You can add a default return value, to return if the iterable has reached to its end.
Iterators don't have a way to get the current value. If you want that, keep a reference to it yourself, or wrap your iterator to hold onto it for you.
