Hy

Lisp and Python should love each other. Let's make it happen.

Hy is a Lisp dialect that's embedded in Python. Since Hy transforms its Lisp code into Python abstract syntax tree (AST) objects, you have the whole beautiful world of Python at your fingertips, in Lisp form.

To install the latest release of Hy, just use the command pip3 install --user hy. Then you can start an interactive read-eval-print loop (REPL) with the command hy, or run a Hy program with hy myprogram.hy.

Hy is tested on all released and currently maintained versions of CPython (on Linux and Windows), and on recent versions of PyPy and Pyodide.
