What is the difference between next() and \_\_next\_\_() in python 2 and 3?

In Python 3, there is no `next()` function as it was removed and replaced with `__next__()`. This function is used to iterate over an object, as it is the built-in Python function for iterators or generators. In Python 2, there are two kinds of constructors for iterators: one uses `next()` and the other uses `yield`.

On the other hand, in Python 3, the `next()` function was removed (along with `raw_input` function) and replaced with the `__next__()` method of an object. As this method is used for iteration, objects that implement iteration also need to have a `__next__()` method. This means that all iterables in Python 3 must have a `__next__()` method, or they should be made iterable.

In summary, the `next()` function in Python 2 is used to iterate over an object, and in Python 3 it is replaced by the `__next__()` method. The `__next__()` method is used to iterate over an object and get the next item in the sequence, whereas `next()` is used for the same purpose in Python 2.

In Python 2, the `next()` function was a built-in function that returned the next available item in a sequence, such as a list or a tuple. In Python 3, the `next()` function was replaced with the `next()` class, which is a type of iterator object that provides the same functionality. The Unified Type Definition (UTD) for `next()` in Python 3 is:
```
class next:
    def __init__(self, iterable):
        self.iterable = iterable
    def __next__(self):
        return next(self.iterable)
```
In Python 3, the `__next__()` method is called when the `next()` object is used as a keyword argument to an iterable object. This method returns the next item in the iterable. 
Therefore, in Python 2, `next()` was a function that returned the next item in a sequence, while in Python 3, `next()` is a class that implements the `__next__()` method to return the next item in an iterable.
