Chapter 26: Advanced Python Programming – Iterators and Generators
Abstract : In Python, iterators and generators are both used for creating sequences of values , but they differ in their implementation and how they generate these values. Iterators are objects that provide sequential access to elements of an iterable, while generators are functions that yield values one at a time. Iterators: Definition: An iterator is an object that implements the __iter__ and __next__ methods. Creation: You can create iterators from iterables (like lists, tuples, strings) using the iter() function. State: Iterators maintain internal state, allowing them to track their position within the sequence. Implementation: Iterators can be implemented as custom classes that define __iter__ and __next__ methods. Generators: Definition: Generators are special functions that use the yield keyword to produce values. Creation: Generator...
