FastKML
A Python library for reading, writing and manipulating KML files.
Introduction
KML is an XML geospatial data format and an OGC standard that deserves a canonical python implementation.
Fastkml is a library to read, write and manipulate KML files. It aims to keep it simple and fast (using lxml if available). Fast refers to the time you spend to write and read KML files as well as the time you spend to get acquainted to the library or to create KML objects. It aims to provide all of the functionality that KML clients such as Marble, NASA WorldWind, Cesium JS, OpenLayers, Google Maps, and Google Earth support.
For more details about the KML Specification, check out the KML Reference on the Google developers site.
Features
Simple and fast: Easy-to-use API with fast performance
Geometry support: Handles geometries as pygeoif objects, compatible with any geometry that implements the __geo_interface__ protocol, such as shapely
Cross-platform compatibility: Tested on CPython, PyPy and GraalPy
Python 3.9+: Works on alternative Python implementations that support Python >=3.9
