6,557 PointsWhat does it mean... "Assign"
I don't know how to Assign array items to a variable.
contact_list = [
{"name" => "Jason", "phone_number" => "123"},
{"name" => "Nick", "phone_number" => "456"}
]
contact_list.each do |item|

Python Web Development Techdegree Student 6,851 PointsHi Zachary,
The variable on the "slide" (i.e. "|item|
") is the named variable used to access the element within the block.
For example:
contacts = ['Bob', 'Jane', 'Sue']
contacts.each do |contact|
puts contact
end
would return
Bob
Jane
Sue
An alternative syntax for this, which avoids the do...end
syntax would be:
contacts = ['Bob', 'Jane', 'Sue']
contacts.each { |contact| puts contact }
Hope that helps!

and why does it keep disconnecting while I'm doing the challenge, then have to restart?
