More languages that compile to Python, besides Coconut and Hy:

• Dogelang https://github.com/pyos/dg “it’s a Python ! No, it’s a Haskell !” v1 in 2015
• Hissp - It’s Python with a Lissp! https://github.com/gilch/hissp created in 2019. “a modular Lisp implementation that compiles to a functional subset of Python”

also:

• https://github.com/i2y/mochi (last commit 2016) “Dynamically typed programming language for functional programming and actor-style programming”
• https://github.com/billpmurphy/hask “Hask is a pure-Python, zero-dependencies library that mimics most of the core language tools from Haskell” (last commit 2015)

Built in another language and compatible with Python:

• Erg, in Rust, statically typed “Erg is internally compatible with Python and can import the Python API at zero cost.” https://github.com/erg-lang/erg

Targetting the Python platform:

• Haxe https://github.com/HaxeFoundation/haxe

my list (not much maintained) https://github.com/vindarel/languages-that-compile-to-python/

This would be a reasonable place to mention Python’s predecessor SetL.

We should start making up new ones:

• Hydra: Python but implemented in Fortran
• Asp: Python but runs on the CLR (okay that’s a real thing but “Iron Python” is a wasted pun)
• Cleese: Python but it’s implemented using materials in the Legend of Zelda to make a virtual CPU
• Terry: Python but it comes with a luxurious washcloth for scrubbing up after work
