In today’s fast-paced world, programmers are always looking for ways to achieve more with less code. In some programming languages such as Java, this would be nearly impossible, but in Python, it’s a lot easier to do — with python one-liners.

One of the most enjoyable aspects of programming with Python one-liners is the opportunity to read and write code that accomplishes a lot in just a few lines. In fact, there’s an entire subculture centered around the challenge of writing the most concise code possible to solve a given problem.

In this blog, we will explore different ways of replacing multi-line Python loops with one-liner functions. Let’s keep the concentration levels high for the next 3 minutes!

We need to know the following 5 concepts to be able to convert most of our multi-line loops with one-liners:

List Comprehension

Lambda Function

Map Function

Filter Function

Reduce Function

Even if you then you have heard about these functions there is no harm in refreshing these concepts.
