 The GeostatsPy Package brings GSLIB: Geostatistical Library (Deutsch and Journel, 1998) functions to Python. GSLIB is extremely robust and practical set of code for building spatial modeling workflows. I need it in Python to support my students in my **Data Analytics**, **Geostatistics** and **Machine Learning** courses.
