Embedding Python in Go

Datadog's Go Agent embeds a CPython interpreter to execute Python checks and custom scripts without requiring recompilation. This integration leverages cgo to bridge Go and C APIs, allowing for programmatic operations like initializing and finalizing the interpreter, importing modules, and calling Python functions. The use of the go-python library abstracts cgo details for a more idiomatic Go experience. The article also discusses the Global Interpreter Lock (GIL) as a consideration for concurrency when embedding Python.
