Pandas library provides data structures designed to handle tabular datasets with simplified Python API.
The name ‘pandas’ is derived from the term ‘panel data’ which refers to multi-dimensional datasets.
Pandas provide efficient data structures like DataFrames and Series, along with functions for data cleaning, transformation and analysis.
Pandas can be easily integrated with other Python libraries.
