I don't think that is a personal preference :)
I mean, in python you'll often see free function like 
len(obj) or dir(), while in ruby you'd do obj.length and obj.methods.

That reflect on other things like hash keys. There are no special type
in ruby, so you can use everything as an hash key.


Another example that suddenly appeared to me: slightly different
lexical closures:
 def make_accumulator (n)
  lambda {|i| n += i }
 end

That is little harder in python cause you don't have access to the
variable 'n' , just his object. 



BTW, as I said, little differences.
