NK_datasets

NK_datasets ships standardized datasets for NPB (Nippon Professional Baseball) and KBO (Korea Baseball Organization), packaged with pandas loaders.
It also includes MLB players who have played in either NPB, KBO, or both.

• NPB data was scraped from the official NPB website and npbstats.com.
• KBO data was scraped from the official KBO website.
• MLB alignment is partial; meaning only players who appeared in KBO/NPB are included. It was sourced from Lahman Database.

Requirements

• Python 3.9+
• pandas 1.5+

Install

pip install nk_datasets
