Python 3 Tutorial: How To Use The Iter Method and Next Method In Python 3

In this Python 3 tutorial, we will look at two methods. First method is the iter() method and the second is the next() method. These two methods work together to create iteration object and iterate through the iteration object. If you have any questions about the iter method or the next method let us know.

The fact that you need to call the __iter__ method first is because the original object has not the __next__ special method in it (try dir() to check). The for loop does this by it's own: it first calls the __iter__ and then the __next__.

If you where to go line by line in a file buit-in type you do not need the __iter__ first step because the type has already the __next__.
