Subject: On Hashes - How the hashes printing works?

Hi All,

I have my code as follows:-

people = {
"torvalds"=>{"lname"=>"Torvalds", "fname"=>"Linus",
"job"=>"maintainer"},  "matsumoto"=>{"lname"=>"Matsumoto",
"fname"=>"Yukihiro", "job"=>"Ruby originator"},
"litt"=>{"lname"=>"Litt", "fname"=>"Steve", "job"=>"troubleshooter"}
}
keys = people.keys
for key in 0...keys.length
print "key  : ", keys[key], "\n"
print "lname: ", people[keys[key]]["lname"], "\n"
print "fname: ", people[keys[key]]["fname"], "\n"
print "job  : ", people[keys[key]]["job"], "\n"
print "\n\n"
end

O/p:-
key  : litt
lname: Litt
fname: Steve
job  : troubleshooter
key  : matsumoto
lname: Matsumoto
fname: Yukihiro
job  : Ruby originator
key  : torvalds
lname: Torvalds
fname: Linus
job  : maintainer

Question:-
Why key of "litt" is printed first thought the first key of hash is
"torvalds"?

Thanks and regards,
Neela.
