The main problem related to finding geometry overlaps in Python is that the library does not provide a straightforward way to identify which polygons overlap. Additionally, the library does not provide a way to determine the extent of the overlap.

Geometry libraries
There are a few Python libraries that focus on geometry. These libraries can be used for a variety of purposes, such as drawing shapes, calculating distances and angles, and more. Some of the most popular Python geometry libraries include:
PyGDX: This library is used for developing games and applications using OpenGL. It includes features for drawing shapes, calculating distances and angles, and more.
NumPy: This library is used for mathematical operations on arrays of numbers. It includes features for working with points, lines, polygons, and more.
