Puts return

Hello guys, i'm new in ruby and i'm trying to create an Address Book.
(I'm from Brasil)
When i put the book to print
"puts lista" #lista is the Address Book
the method to_s of the AddresBook class is like this:
"def to_s
  puts "Lista Telefonica"
  puts "Numero de Contatos: " + @qtContatos.to_s
  @persons.each do |pessoa|
  #persons is an array of a Class Person that have it's own to_s method
    puts pessoa
    puts ""
  end
end
"

It's working well, but when I run it in the cmd:
"C:\Users\Dudu\.gem\exe>ruby ListaTelefonica.rb"
(I'm using Windows 7 with Gems version "1.3.5")

The print Returns the & (address) of each thing I print...
example:
"
Nome: My Name
Email: myemail@this.com
Fone: XXXXXXX
Endereco:
     Rua NumSei, 321
     Cidade: Anyone
     Pais: Brasil
#<Address:0x2803ae0>
#<Pessoa:0x2803b20>

#<AddressBook:0x28043a0>
"

How can I take this Address out??
this "#<AddressBook:0x28043a0>" and the others
:S
Thanks!!!

Hello guys, i'm new in ruby and i'm trying to create an Address Book.

@persons.each do |pessoa|
#persons is an array of a Class Person that have it's own to_s method
   puts pessoa
   puts ""
end

First of all, method to_s() should *return* a string, not print it. So, remove puts() from to_s() and simply return a string. In your case, return from to_s() is the content of your @persons array, it gets printed by your "puts lista" statement.

You can do something like the following:

def to_s
  [
    "Lista Telefonica",
    "Numero de Contatos: #{@qtContatos}",
    @persons.map { |pessoa|
      pessoa.to_s
    }
  ].join("\n")
end

Then, if to_s() for objects in your @persons array is defined accordingly, you should have a nice looking output.
