You can write lisp-y python quite easily. It's not good, pythonic or maintainable, but for learning purposes it is acceptable, especially on the 2.x series. Just start with list comprehensions.
Lua and Ruby I fail to see how they are in any way lisp-y.
Ruby: Almost everything is an expression unlike Python, has symbols unlike Python, closures and anonymous functions are not crippled or second-class unlike Python, has full continuations unlike Python.
Lua: Simple, minimal syntax which is consistent (unlike Python), multiparadigm, designed around one core datastructure, metatables/metamethods, metaprogramming is encouraged, has environments.
If by lispy you mean data oriented code with functions instead of classes and composition, I'd argue that it's not only pythonic, but import this compliant.
I got the impression that Hy is stagnating. They removed 'let' in the recent releases (it's hard to imagine Lisp without 'let'). Also there is no support for async, which is pretty important for modern Python IMO.
