Chapter 26: Advanced Python Programming – Iterators and Generators

Image
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...
