Ruby Ruby Collections Build a Grocery List Program Create a Method That Returns a Hash

seriously confused... asking to create simple method "create_shopping_list" and only return a hash... not working...

in the build a grocery list program, stage 3 challenge... it asks for a simple method called "create_shopping_list" with no standard inputs, just return the hash...

def create_shopping_list

hash = { "name" => name }

return hash end

what's wrong with this code?

shopping_list.rb 
def create_shopping_list
  hash = { "name" => name, "items" => Array.new }
  return hash
end

I would write it like this: 

def create_shopping_list 
     hash = Hash.new
    return hash
end

and then call it:

create_shopping_list

This is actually pretty simple, it just ask you to return a hash, any hash would do, including an empty hash. :smiley:

def create_shopping_list
  {}
end

And the problem of your code is this line "name" => name, you'll get a NameError exception because name is undefined.
