How to choose between Pandas and Polars for python data projects.
Pandas and NumPy have long been the open source dynamic duo of python data science.
They provide flexible data structures that can handle a wide range of data types including tabular data, time series data, and more.
They also provide a wide range of data analysis, data cleaning, data transformation, data aggregation, and data visualization tools.
And while they generally provide a performance boost over pure python implementations, they are still single threaded and so cannot take advantage of even moderately contemporary hardware.
This is being addressed by the Polars project which is a rust-based python library that leverages Apache Arrow and parallel procesing on multicore CPUs.
The best description Ive found for this comes from here or, if you like videos, Ritchie Vink explains it well Tell me why. [ 1 remarks ]
