Hi,

Is the following  what you try to do?


Li

##script
#:england and :france (or :England and :France) are symbols in ruby

liverpool='Liverpool'
london='London'
plymouth='Pymouth'
rennes='Rennes'
paris='Paris'


hash = {
      :england => [liverpool, london, plymouth],
      :france => [rennes, paris]
}

 puts hash.fetch(:england)[0]
puts hash.fetch(:england)[2]

#output
>ruby forum3.rb
Liverpool
Pymouth
>Exit code: 0
