In the world of Python data science, Pandas is the gold standard for data manipulation. However, as datasets grow into the millions of rows, standard operations like .apply() can become a major bottleneck because they typically run on a single CPU core. pandarallel

: Certain steps in machine learning pipelines, like data preparation and feature engineering, can benefit from parallelization.
