Deep dives
Overview of Data Frame Libraries
Data frame libraries are crucial in data science, and while Pandas is the most recognized, alternatives like QDF, Moden, Polars, and Dask offer distinct features and APIs. Each library has its unique strengths, for example, Polars is known for its optimized performance. The problem arises for developers looking to write libraries compatible with multiple frameworks, as the APIs can differ significantly, both in functionality and behavior. Narwhals aims to bridge this gap by offering a compatibility layer that allows tool builders to create libraries that work seamlessly across different data frame libraries.
