33,317 PointsHash and Array Iteration
I don't understand what I'm doing wrong? Can someone help me? The question is: Using the each method, iterate over the contact_list array. Assign each array item to the local variable contact in the block and print out the value of the name and phone_number keys.
This is my code:
contact_list = [
{"name" => "Jason", "phone_number" => "123"},
{"name" => "Nick", "phone_number" => "456"}
]
contact_list.each do |contact|
puts "Name: #{contact["name"]}"
puts "Phone Number: #{contact["phone_number"]}"

36,441 PointsYou're close, but they only want the values,without any additional stuff, like this:
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

contact_list = [
{"name" => "Jason", "phone_number" => "123"},
{"name" => "Nick", "phone_number" => "456"}
]
contact_list.each do |items|
items.each do |key, value|
puts "name"
puts "phone_number"
end
end

25,199 PointsI tried it a different way,
contact_list.each do |x|
x.each_pair do |key, value|
puts key
puts value
end
end
According to the tutorial but it doesn't work. Any ideas why?

5,110 Points@Saad Khan Malik it has to be like this:
contact_list.each do |x|
x.each_pair do |key, value|
puts "name"
puts "phone_number"
end
end
You just had to use "name" and "phone_number"
