Question

So let me reform this question:

I have two hashes I’m comparing against. At some point in my code I get a response such as..

@moves = {:wm01 => {:a1=>"O", :a2=>" ", :a3=>" ", :b1=>" ", :b2=>"O", :b3=>" ", :c1=>" ", :c2=>" ", :c3=>" "}

This corresponds to an answer key hash…

@anskey={
    :wm01=>":c3",:wm02=>":c2",:wm03=>":c1",:wm04=>":b3",:wm05=>":b1",:wm06=>":a3",:wm07=>":a2",:wm08=>":a1",
    :wm09=>":a3",:wm10=>":c1",:wm11=>":a1",:wm12=>":c3",:wm13=>":c3",:wm14=>":c1",:wm15=>":c3",:wm16=>":a1",
    :wm17=>":b1",:wm18=>":b2",:wm19=>":b3",:wm20=>":a2",:wm21=>":b2",:wm22=>":b2",:wm23=>":c2",:wm24=>":b2"
  }

in this case I need to iterate @anskey where @moves.keys == @anskey.keys

(hmmm. I may have just answered my own question)

and then set….

my_answer_is = @anskey.value

Hope this is clearer.

Original “question” below:

It’s been a long day and I’m getting screen fatigue…

I have this…

str = [:wm24]

want to say…

@anskey[:wm24]

this is wrong..

@anskey[str]

what is right?

@anskey[?]

Answer 1

You can pass it the first element from the array like this:

@anskey[str.first]

Or if you want to access an element based on its index (position in the array), you count up from zero. So in this case:

@anskey[str[0]]
