Hello,

str = "hello world"
str[0]  # -> 104

it's the ASCII code of the caractere


What does 'str[0]' do?  Why does it print 104 instead of "h"?

I realize that these work:

str[0..0] # -> "h"
str[0,1]  # -> "h"

ok, it's the substring


Could someone explain to me what these do?  And why I get:

str[0,0] # -> ""

and str[0,1]



Thanks a lot,
Daniel.
