Hi there.

I’m coming to ruby mainly from python background.

in python  
a = b = range(10)

will yields two names pointing to the same object

but in ruby

a = b = Range.new(0,9)

will yield two two distinct objects.

To get the effect of the python line in ruby it seems I have to do:  
b = Range.new(0,9)  
a = b

What’s the logic behind that?

See this session:

irb(main):001:0\> a = b = Range.new(0, 9)  
=\> 0…9  
irb(main):002:0\> a.object\_id  
=\> 1744024  
irb(main):003:0\> b.object\_id  
=\> 1744024

Actually, it won’t.

How did you come to this conclusion?

Did just that. Should have done it twice I guess 🙂
