In this tutorial, you’ll learn about functional programming in Python. You’ll see what functional programming is, how it’s supported in Python, and how you can use it in your Python code.
Functional programming is a programming paradigm in which the primary method of computation is evaluation of functions. In this tutorial, you’ll explore functional programming in Python.
Functional programming typically plays a fairly small role in Python code. But it’s good to be familiar with it. At a minimum, you’ll probably encounter it from time to time when reading code written by others. You may even find situations where it’s advantageous to use Python’s functional programming capabilities in your own code.
In this tutorial, you’ll learn:
- What the functional programming paradigm entails
- What it means to say that functions are first-class citizens in Python
- How to define anonymous functions with the lambda keyword
- How to implement functional code using map(), filter(), and reduce()
