Pandas is an open source Python-based data analysis and manipulation library that provides powerful data structures and tools for quickly analyzing and manipulating data. It has a wide range of functions for handling tabular, unstructured, and time series data sets. Pandas allows users to easily manipulate and analyze large datasets with minimal programming or scripting required. It also enables efficient access to specific subsets of the dataset’s information. Additionally, pandas supports both loading from flat files (csv, excel) as well as from databases and other sources such as HTML tables or JSON files.
