Pandas is a well-established Python library for data analysis and manipulation on labeled datasets since 2008, designed to provide a high-level foundation for real-world data analysis. It allows for aligning, merging, and transforming data while loading from various sources. Polars emerged in 2020 as a newer alternative, focusing on performance gains, utilizing machine cores efficiently, optimizing queries, and handling large datasets beyond RAM constraints. Both libraries share similarities in handling tabular data but are positioned differently in terms of performance and capabilities.
Pandas is a Python library used for data analysis and manipulation on labeled datasets. The core mission of the Pandas development team is to be the fundamental high-level building block for practical, real-world data analysis in Python. It provides tools and methods for aligning, merging, transforming, and managing data from various persistent stores, positioning itself as the definitive tool for data analysis in Python.
Polars, which is relatively new, originated in 2020, and works similarly to Pandas. It offers tools and methods for aligning, merging, transforming, and loading data from various formats. Some key goals include utilizing all available cores on the machine, optimizing queries, and handling datasets larger than the available RAM, while maintaining a consistent API and adhering to a strict schema.
