How to make a custom object iterable in python?

To make a custom object iterable in Python, you need to define an __iter__() method within the class. This method should return an iterator object that defines the __next__() method to retrieve the next item from the iterable. Here's a step-by-step guide:

  • Define your custom class:
class MyIterable: def __init__(self, data): self.data = data self.index = 0 def __iter__(self): return self def __next__(self): if self.index < len(self.data): value = self.data[self.index] self.index += 1 return value else: raise StopIteration
  • Use the custom iterable:

Now you can create an instance of your custom iterable class and use it in a for loop or with other iterable-related operations:

my_iterable = MyIterable([1, 2, 3, 4, 5]) for item in my_iterable: print(item)

This code will print:

1 2 3 4 5

Your custom iterable class can be extended to provide more advanced behavior or support various iteration patterns. The example above implements a basic iterable with a simple list of data. You can customize the __next__() method to suit your specific requirements.

Remember that in Python 3, you don't need to define __next__() as next() is a built-in function that calls __next__() automatically. In Python 2, you'd define next() as well.
