Why make an iterator? Making an iterator: the. Generators: the easy way to. Under the hoo the generator object supports the iterator protocol and does something roughly similar to the class Counter. How to make a custom object iterable?

Can I iterate over a class in Python ? Custom classes created by us are by default not Iterable. If we want to iterate over the objects of our custom class then we need to make them . Iterable): def __iter__(self): pass class SomeIterable2: def . As you have learned in the Python. Type object for iterator objects returned by PySeqIter_New() and the one- argument form of the iter() built-in function for built-in sequence types. Here is an iterator that works like built-in range function.

Iterators are implemented as classes. The iterator protocol is a Python class which comes with two special methods, namely __iter__() . Counter(object): def __init__(self, low, high): self. Python is fully object-oriented: you can define your own classes , inherit from your own . To create a Python iterator object, you will need to implement two methods in your iterator class.
