I am a newbie but I’m familial with C#.
I can’t find any dictionary class in Ruby.
I need to do like Dictionary<key, List>
Can I do that in Ruby? If yes, how?
Big thanks!

I think what you seek is Hash.

my_hash = {
‘fruits’ => [‘apple’, ‘pear’],
‘cars’ => [‘VW’, ‘BMW’, ‘Ford’]
}
p my_hash[‘cars’]
–output:–
[“VW”, “BMW”, “Ford”]
my_hash[10] = [1, 2, 3]
p my_hash
–output:–
{“fruits”=>[“apple”, “pear”], “cars”=>[“VW”, “BMW”, “Ford”], 10=>[1, 2,
3]}
In ruby, keys and values for a hash can be anything, and you can freely
mix types. In ruby 1.9, hashes are now ordered–in the order the keys
were added.
