Iterators and Iterables in Python: Run Efficient Iterations
Python’s iterators and iterables are two different but related tools that come in handy when you need to iterate over a data stream or container. Iterators power and control the iteration process, while iterables typically hold data that you want to iterate over one value at a time.
Iterators and iterables are fundamental components of Python programming, and you’ll have to deal with them in almost all your programs. Learning how they work and how to create them is key for you as a Python developer.
In this tutorial, you’ll learn how to:
- Create iterators using the iterator protocol in Python
- Understand the differences between iterators and iterables
- Work with iterators and iterables in your Python code
- Use generator functions and the
yieldstatement to create generator iterators
- Build your own iterables using different techniques, such as the iterable protocol
- Use the
asynciomodule and the
asynckeywords to create asynchronous iterators
