Ruby Ruby Loops Build a Simple Contact List Hash and Array Iteration

Need Help

I need help with this question.

contact_list.rb
contact_list = [
  {"name" => "Jason", "phone_number" => "123"},
  {"name" => "Nick", "phone_number" => "456"}
]

contact_list.each do |contact|
  contact = contact_list.each.inspect 
  print contact.inspect
end

You don't need to explicitly assign anything to contact. In each iteration of the loop contact will be one of the hashes in the contact_list array. You need to print the value of the name and phone_number keys of each hash by using square brackets after the name of the variable containing the hash, which is contact, and providing the name of the key inside the square brackets:

contact_list = [
  {"name" => "Jason", "phone_number" => "123"},
  {"name" => "Nick", "phone_number" => "456"}
]

contact_list.each do |contact|
  puts contact['name']
  puts contact['phone_number']
end

Yeah, this totally helped. Just by the by how do you link your code to replies?

Alistair Mackay - Use three backticks, ```, followed by the name of the language, python for example, then another three backticks after the last line of code.

Bingo thanks Kourosh,

something like this:

string = "hello world"

Yes, except I'm not sure why you have the &quot.

Yeah me neither, it seems to be linked with anything that has speech marks (" "). But thanks, I think I'm getting the hang of this now.
