How do I create an iterable in Python?

You can create an iterable in Python by defining a class with the __iter__() and __next__() methods.

Can you give me an example of a custom iterable?

Sure! Here's a simple example:

class MyIterable:
    def __init__(self, max):
        self.max = max
        self.current = 0

    def __iter__(self):
        return self

    def __next__(self):
        if self.current < self.max:
            self.current += 1
            return self.current - 1
        else:
            raise StopIteration

How do I use this iterable in a loop?

You can use it in a for loop like this:

for number in MyIterable(5):
    print(number)
``` This will print numbers from 0 to 4.

What if I want to create an iterable that returns even numbers?

You can modify the __next__() method to return only even numbers. Would you like to see that example?
