Pandas
Pandas is a free, open-source Python library for data manipulation and analysis, featuring powerful data structures like Series and DataFrames. It enables importing, cleaning, transforming, and analyzing data from a variety of file formats, and supports advanced operations such as grouping, merging, and time series analysis. Built on top of NumPy, pandas brought R-like DataFrame capabilities to Python, making it a cornerstone tool for data science and analytics. While widely used, it is sometimes criticized for memory inefficiency and limited parallel computing support.
