## What it is
gpython is a partial re-implementation and port of the Python 3.4 interpreter written in Go, including a lexer, parser, compiler, and runtime. It is designed to be embedded into Go applications with support for multiple concurrent interpreter instances, though it lacks most of the standard library's C-based modules.

## Use cases
- embed a Python interpreter in a Go application
- run Python scripts from Go code
- run multiple isolated Python interpreter instances concurrently
- experiment with interpreter and compiler implementation in Go
- use a Python REPL without installing CPython

## When to choose
- you need to embed a familiar scripting language into a Go application
- you need multiple independent interpreter contexts in a server
- you want to study or hack on a Python interpreter written in Go

## When to avoid
- you need a full CPython replacement with the complete standard library
- you need maximum Python execution speed
- you rely on C-extension modules like numpy or pandas

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: interpreter, parser, compiler
- domain: programming-languages, parsers, developer-tools
- platform: go, cross-platform, cli
- tags: python-implementation, embedding, repl, python-in-go, interpreter
