pandas

pandas (v3.0+) is Python's primary library for in-memory tabular data analysis. It provides DataFrame and Series as core structures with vectorized operations, I/O adapters, groupby, merging, and time-series support.

Core Data Structures

DataFrame - 2-dimensional labeled table with columns of potentially different types.

Series - 1-dimensional labeled array; a single column or row of a DataFrame.
