Since Polars is built in Rust, and has language bindings for Python, R, SQL, javascript, and Julia, you might be wondering why we focus on its Python API. According to the 2024 Stack Overflow Developer Survey, Python is the most popular programming language among respondents who are learning to code and the fourth most popular among professional developers. This is not surprising, since Python is known for its simplicity, readability, and versatility and is widely used in Data Science, Machine Learning, web development, and more. This popularity is reflected in the Polars community, where the Python API is the most complete, most used, and most updated API. Furthermore, Python is widely regarded as the language of choice for data analysis and data processing, and most data scientists and data engineers are familiar with it.
With this definitive guide at your side, you'll be able to: Process larger-than-memory datasets at record speed Apply the eager, lazy, and streaming APIs of Polars and decide when to use them Transition smoothly from pandas or Spark to Polars Integrate Polars into your existing code base Work with Arrow and Parquet to efficiently read and write data Translate complex ETL tasks into efficient and elegant queries
