Python generator is a simplified way of creating iterators. Let’s explore generators in this article.
What is Generator?
Generators in Python are used to build iterators. It aids in traversing all of the objects/items/values one by one. The generators do not produce all the items at once, rather they produce them one at a time and only when the item is required.
How to Create a Generator in Python?
In Python, we can use the below methods to create a generator function.
- Generator Function (Uses yield statement)
- Using Generator Expression
Generator Function
Generators which give a sequence of values when iterated over and which is helpful in traversing lists or tuples are created using Python’s generator functions.
Python generator functions lets you define a function that behaves like a generator (in effect an iterator).
Generator function is a faster, cleaner and easier way to define a Generator. Generator is an iterable which will return an iterator.
