A programming language similar to Python that compiles to Rust or Go will be amazing.

What benefit would it bring? There's already https://cython.org/ https://cython.org/

  You want to use the Go runtime for example

  Cython uses C-API. This one doesn't.

Spy (https://github.com/spylang/spy https://github.com/spylang/spy) is an early version of this kind of thing. I believe it compiles to C though, kinda like Nim. Actually speaking of Nim, that's probably the most mature language in this space, although it's less pythonic than Spy

Here you are. https://github.com/google/grumpy https://github.com/google/grumpy Last commit was 9 years ago though, so targets Python 2.7.

  Amazing people still keep discovering it. And google search fails to surface working implementations. "Python to rust transpiler" -> pyrs (py2many is a successor) "Python to go transpiler" -> pytago Grumpy was written around a time when people thought golang would replace python. Google stopped supporting it a decade ago. Even the 2022 project by a high school student got more SEO https://github.com/py2many/py2many/issues/518 https://github.com/py2many/py2many/issues/518

Mojo is a language with Pythonic syntax that compiles to fast machine code built by the creator of Swift: https://www.modular.com/open-source/mojo https://www.modular.com/open-source/mojo

  Hold up... did I miss something, is Mojo open sourced now? Edit: No it is still not open source. There are still same promises of open sourcing eventually, but there is no source despite the URL and the website claiming it's an open language. What's "open" here is "MAX AI kernels", not Mojo. They refer to this as "750k lines of open source code" https://github.com/modular/modular/tree/main/max/kernels https://github.com/modular/modular/tree/main/max/kernels This feels icky to me.

    The compiler will be open-sourced in a few months.

      There is a question of what benefit would it bring even if its open sourced? Static python can transpile to mojo. I haven't seen an argument on what concepts can only be expressed in mojo and not static python? Borrow checker? For sure. But I'm not convinced most people need it. Mojo therefore is a great intermediate programming language to transpile to. Same level of abstraction as golang and rust.

        Python has a performance problem. Most people may not need it, but many people do. Languages like Rust and Go are heavily adopted by Python programmers either trying to understand low-level concepts or looking for something more performant. And this is before we talk about the real selling point, which is enabling portable heterogenous compute.

F# is very similar to python because it's based on indentation instead of curly braces. And with Fable you can transpile it to Rust (or Python even): https://github.com/fable-compiler/fable https://github.com/fable-compiler/fable

Nim looks a lot like Python with a first-class type system and compiles to many different targets, including wasm and C.
