Pandas is a powerful Python library widely used for data manipulation and analysis, particularly in handling structured data. It provides easy-to-use data structures, such as DataFrames, which allow for efficient handling of tabular data and support operations like filtering, grouping, merging, and aggregating. Pandas simplifies working with large datasets, offering tools to clean, transform, and analyze data quickly. Its intuitive API and integration with other libraries make it a key tool for data science, data engineering, and machine learning tasks.
