What is the use of the "iter" method in Python?

The **iter** method in Python is used to define an object that can be iterated, such as a list or a dictionary. The **iter** method returns an iterator object that implements the iterator protocol, which consists of the methods **__next__** and **__iter__**. The **__next__** method returns the next item in the sequence, and raises a **StopIteration** exception when there are no more items to be returned. The **__iter__** method returns the iterator object itself, which allows an object to be used as an iterable in a **for** loop or with the **next** function. To create an iterable object, you can define a class that implements the **iter** method and returns an iterator object, or you can use a generator function.
