Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). [2] [3] Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte. [4] Lisp allows operating on code as data (metaprogramming), thus Hy can be used to write domain-specific ...
Lisp source code is made of lists. Thus, Lisp programs can manipulate source code as a data structure, giving rise to the macro systems that allow programmers to create new syntax or new domain-specific languages embedded in Lisp. The interchangeability of code and data gives Lisp its instantly recognizable syntax. All program code is
Lisp was the first language where the structure of program code is represented faithfully and directly in a standard data structure—a quality much later dubbed "homoiconicity". Thus, Lisp functions can be manipulated, altered or even created within a Lisp program without lower-level manipulations.

A Lisp compiler generates bytecode or machine code from Lisp source code. Common Lisp allows both individual Lisp functions to be compiled in memory and the compilation of whole files to externally stored compiled code (fasl files). Several implementations of earlier Lisp dialects provided both an interpreter and a compiler.
In Python, it is the <__module__.class instance> notation, and in Common Lisp, the #<whatever> form. The REPL of CLIM, SLIME, and the Symbolics Lisp Machine can also read back unreadable objects. They record for each output which object was printed. Later when the code is read back, the object will be retrieved from the printed output.
The programming language Lisp is the second-oldest high-level programming language with direct descendants and closely related dialects still in widespread use today. The language Fortran is older by one year. [1] [2] Lisp, like Fortran, has changed a lot since its early days, and many dialects have existed over its history.
Logo is a multi-paradigm adaptation and dialect of Lisp, a functional programming language. [3] There is no standard Logo, but UCBLogo has the best facilities [ according to whom? ] for handling lists, files, I/O, and recursion in scripts, and can be used to teach all computer science concepts, as UC Berkeley lecturer Brian Harvey did in his ...
