What is Pandas?

A powerful data analysis and manipulation library providing DataFrames and tools for working with structured data.

Pandas is the cornerstone of data analysis in Python. DataFrames organize data into rows and columns (like spreadsheets). Key operations include reading CSV/Excel/SQL data, filtering, grouping, merging, pivoting, and statistical analysis.

Built on NumPy, Pandas handles missing data, time series, and large datasets efficiently. Common methods include .head(), .describe(), .groupby(), .merge(), .apply(), and .to_csv(). It is essential for data science, analytics, and machine learning workflows.
