## What it is
py2many is a Python-based source-to-source transpiler that converts Python code into multiple statically-typed languages including Rust, C++, Go, Zig, Julia, Kotlin, Nim, Dart, V, D, Mojo, and Lean. It uses Python's AST to perform type inference and emit idiomatic code in target languages.

## Use cases
- convert python code to rust for better performance
- transpile python to c++ for systems programming
- share library code across mobile platforms without rewriting
- learn a new language by comparing python source with transpiled output
- write security-sensitive code in python and transpile to rust
- add inferred type annotations to python code
- generate go or kotlin from python algorithms

## When to choose
- you have typed, testable python code you want to run faster in a compiled language
- you need to port python algorithms to rust, c++, or go without manual rewriting
- you want a learning aid showing python equivalents in other languages

## When to avoid
- your python code relies heavily on dynamic features, metaprogramming, or third-party libraries
- you need fully idiomatic production code in the target language without manual cleanup
- you need runtime python execution rather than translation

## Facets
- artifact type: library
- maturity: active
- function: compiler, parser, developer-tools, type-system
- domain: programming-languages, compilers, developer-tools, parsers
- platform: python, cli, cross-platform
- tags: transpiler, python-to-rust, python-to-cpp, python-to-go, code-generation, ast, source-to-source
