Using Polars For Data Analytics

Most Data Scientists/Analysts using Python are familiar with Pandas. And if you are in the data science field, you probably have invested quite a significant amount of time learning how to use them to manipulate your data. However, one of the main complaints about Pandas is its speed and inefficiencies when dealing with large datasets. Fortunately, there is a new dataframe library that attempts to address this main complaint about Pandas — Polars.

Polars is a DataFrame library that is completely written in Rust. In this article, I will walk you through the ins and outs of using Polars in Python and how it can be used in place of Pandas.


  • Comparing Pandas and Polars
  • Loading a Polars DataFrame
  • Selecting columns and rows
  • Lazy Evaluation in Polars
  • Manipulating values in dataframe
  • Data cleansing
  • Performing GroupBy functions
