How to Use Python Lambda Functions

This in-depth tutorial will teach you how to use Python Lambda functions. You’ll understand why they help simplify code in the context of functional programming. Also, you’ll get acquainted with basic use cases of lambda functions, as well as advanced ones.
Lambda functions are essentially small anonymous functions suitable for situations where you need a simple function for a short time. You create these types of functions right where you need them. They are usually compact and just one-liners. Lambda functions make your code clean and easier to follow.
Unlike the traditional functions where the Python keyword, def
, comes into play, you create this kind of function using the keyword, lambda
. You’ll learn the syntax of lambda functions shortly.
Prerequisites
This tutorial is for beginner to intermediate Python programmers. However, it’s simple enough for curious minds who aren’t within the range but are interested in Python lambda functions or programming in general to follow along.
You’ll need:
- Python ≥ version 3.0.0
- Any code editor (Pycharm is recommended)
