Sep 25, 2019 In this step-by-step tutorial, you'll learn about generators and yielding in Python. You'll create generator functions and generator expressions using multiple Python yield statements. You'll also learn how to build data pipelines that take advantage of these Pythonic tools. This article describes the difference between list comprehensions and generator expressions; provides simple examples from basic to complex concepts. Lists are mutable in Python. This means you can replace, add or remove elements. Function context/state has to be saved to be picked up next time for generating next value. That “saving. Python generators are a simple way of creating iterators. All the overhead we mentioned above are automatically handled by generators in Python. Simply speaking, a generator is a function that returns an object (iterator) which we can iterate over (one value at a time).
