You may be over thinking it. I think this is the answer you want:

contact_list = []

contact = {"name" => get_name(), "phone_number" => get_phone_number() }

contact_list.push(contact)

I don't know what you are attempting to do here, but are you intending to push get_name() and get_phone_number() onto your contact_list before pushing the contact? You call .push twice and then you use the << push operator at the end.

I suspect you intend to do this:

contact_list = []

contact = {"name" => "", "phone_number" => "" }

contact["name"] = get_name()
contact["phone_number"] = get_phone_number()

contact_list << contact

The code as you have it results in contact_list having three elements at the end. The result of get_name(), the result of get_phone_number(), and the contact.

This'll work too:

contact_list = []

contact = {"name" => get_name, "phone_number" => get_phone_number }

contact_list.push(contact)
