Pandas
Fast, flexible data analysis library — DataFrames, time series, and data wrangling for Python.
Pandas is the foundation of Python data science — its DataFrame structure brings SQL-like operations (groupby, merge, pivot) and time series handling to Python. It reads and writes CSV, Excel, SQL, Parquet, and JSON. For larger datasets, Polars and Dask offer faster or distributed alternatives with a similar API.
