Question

Programming Language: What language has both Python & Ruby features?

Answer 1

+2 A:

I don't understand what you mean by "everything is an object", as far as I know Python has no primitives either (you can derive from the basic integer type in Python 3 for example.)

I've used both, and although I prefer Python, Ruby is no doubt a very potent language, so instead of going by a chart, install both and see which you prefer programming in. If you still can't decide, look at the surrounding environment (how good is the standard library, tools, docs etc.)

Ruby and Python has different "idioms", and underlying philosophies which most probably differs on some points, which might be worth investigating.

"everything is an object" means that classes and functions are instances too.

Odomontois 2010-08-15 21:46:30

Well they are, `type(a)` where a `def a(): pass` yields `<class 'function'>`, `type(int)` yields `<class 'type'>`. A class is an instance of type.

@Skurmedel - Even better, a class can be an instance of anything, it's just that most classes are instances of type. So you can have metaclasses.

In Python, you can't do things like: 5.toString()

TeddyB 2010-08-15 22:02:54

Because 5 is an immutable object. Just type dir(5) at the interactive prompts, and you'll see the methods defined on it. And, by the way, you can do something like getattr(5, '__repr__')() to get the same you were talking about.

Roberto Liffredo 2010-08-15 22:08:35

@TeddyB - that is only because the python parser interprets `5.` as a floating point number. This works: `(5).__str__()`

Omnifarious: Yup, you can do some nice things with metaclasses.

Skurmedel 2010-08-15 22:39:20

I think I know what you mean by "everything's an object", you mean they derive from Object in Ruby. That is true, but in the sense of the object model, everything is still an object in Python as it is in Ruby.

Skurmedel 2010-08-15 22:48:26

Python has only two primitives: `type` and `object`. They are like Python's yin and yang; `type` inhertis from `object` but `object`'s metaclass is `type`. Together they form the base of the Python (new-style classes) object system.

Answer 2

A:

Check out groovy. Also it has great feature that have Python and Ruby and some other popular langages, but most of dynamic languages lacks - IDE support ( by NetBeans, Eclipse and IDEA ). Differences from python and differences from ruby
