What are some iterable design patterns in Python?

In Python, iterable design patterns include the Iterator, Iterable, and Generator patterns. Would you like to know more about each?

Yes, please explain the Iterator pattern.

The Iterator pattern allows sequential access to elements of a collection without exposing its underlying representation. In Python, this is implemented using the __iter__() and __next__() methods.

Can you give me an example of how to implement an Iterator?

Sure! Here's a simple example:

class MyIterator:
    def __init__(self, data):
        self.data = data
        self.index = 0

    def __iter__(self):
        return self

    def __next__(self):
        if self.index < len(self.data):
            result = self.data[self.index]
            self.index += 1
            return result
        else:
            raise StopIteration

That's helpful! What about Generators?

Generators are a simpler way to create iterators using the yield keyword. They allow you to iterate over data without storing the entire collection in memory.
