py2many: Python to Rust, C++, Go, Zig, Mojo & More - Universal Python Transpiler
Convert Python code to Rust, C++, Go, Zig, Julia, Nim, Dart, and other languages automatically
py2many is a powerful Python transpiler that converts Python source code into multiple statically-typed programming languages. Transform your Python code to Rust for performance, C++ for systems programming, Go for concurrency, or Kotlin for mobile development.
Why Convert Python to Other Languages
Performance: Python is popular and easy to program in, but has poor runtime performance. Transpiling Python to Rust, C++, or Go can dramatically improve execution speed while maintaining the development experience of Python.
Security: Writing security-sensitive code in low-level languages like C is error-prone and could lead to privilege escalation. With py2many, you can write secure code in Python, verify it with unit tests, then transpile to a safer systems language like Rust.
Cross-platform Development: Accelerate Python code by transpiling it into native extensions or standalone applications.
Mobile & Systems Programming: While Swift and Kotlin dominate mobile app development, there's no universal solution for sharing lower-level library code between platforms. py2many provides an alternative to Kotlin Mobile Multiplatform (KMM) by letting you write once in Python and deploy to multiple targets.
Learning Tool: It's an excellent educational tool for learning new programming languages by comparing Python implementations with their transpiled equivalents.
Supported Languages & Status
Primary Focus: Python to Rust conversion with the most mature feature set and active development.
Production Ready: Python to C++ transpilation (C++14 historically supported, C++17+ required for advanced features).
Beta Support: Python to Julia, Python to Kotlin, Python to Nim, Python to Go, Python to Dart, Python to V, and Python to D transpilation.
Type Inference: py2many can also emit enhanced Python 3 code with inferred type annotations and syntax improvements for better code analysis.
Python to Rust Example
See how py2many converts Python code to idiomatic Rust:
Original Python code:
if i == 0 or i == 1:
return 1
return fib(i - 1) + fib(i - 2)
# Demonstrate overflow handling
def add(i: i32, j: i32):
return i + j
Transpiled Rust code:
if i == 0 || i == 1 {
return 1;
}
return (fib((i - 1)) + fib((i - 2)));
}
// return type is i64
pub fn add(i: i32, j: i32) -> i64 {
return ((i as i64) + (j as i64)) as i64;
}
