5 Uses of Lambda Functions in Python

Introduction

The lambda function, which is also called the anonymous function, is one of the core concepts in functional programming.

Python, which supports multi programming paradigms, also gives us a simple way to define a lambda function.

The template of writing the lambda function in Python is:

lambda arguments : expression

It contains three parts:

• A lambda keyword
• Arguments that the function will receive
• An expression whose result is the return value of the function

Because of its simplicity, the lambda functions can make our Python code more elegant in some using scenarios. This post will demonstrate 5 common uses of lambda functions in Python and explain them with interesting examples.

Use 1: Give It a Name and Use It As Normal

If we just need a simple function, lambda is a good choice, since it can be treated as a simpler way to define a function. Therefore, we can give it a name and use it like a normal function.
