I need help with this question.
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 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

something like this:
string = "hello world"

23,733 PointsYes, except I'm not sure why you have the ".

7,812 PointsYeah 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.

23,733 PointsAlistair Mackay - Use three backticks, ```, followed by the name of the language, python for example, then another three backticks after the last line of code.
