Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte.[1] Similar to Kawa's and Clojure's mapping of s-expressions onto the Java virtual machine (JVM),[2] Hy is meant to operate as a transparent Lisp front end to Python's abstract syntax.[3] Lisp allows operating on code as data (metaprogramming). Thus, Hy can be used to write domain-specific languages.[4] Hy also allows Python libraries, including the standard library, to be imported and accessed alongside Hy code with a compiling[5] step converting the data structure of both into Python's AST.[6][7][8][9] Example codeFrom the language documentation:[10] => (print "Hy!") Hy! => (defn salutationsnm [name] (print (+ "Hy " name "!"))) => (salutationsnm "YourName") Hy YourName! See also
