摘要: No need to run loops in Python anymore
Introduction
Loops are expensive(slow) in Python and if you are working with a large number of rows then it’s a crime. In this blog, I will take you through the theory and practical examples of the functions that you can use as an alternative to loops in python.
We will cover the following functions :
1. Map
2. Filter
3. Reduce
Even if you then you have heard about these functions there is no harm in refreshing these.
Before starting with the above functions, let’s have a quick look at the lambda function if you are not already familiar with it.
