ruby - Combine two Arrays into Hash

Question

I've got two Arrays:

members     = ["Matt Anderson", "Justin Biltonen", "Jordan Luff", "Jeremy London"]
instruments = ["guitar, vocals", "guitar", "bass", "drums"]

What I would like to do is combine these so that the resulting data structure is a Hash like so:

{"Matt Anderson"=>["guitar", "vocals"], "Justin Biltonen"=>"guitar", "Jordan Luff"=>"bass", "Jeremy London"=>"drums"}

Note the value for "Matt Anderson" is now an Array instead of a string. Any Ruby wizards care to give this a shot?

I know Hash[*members.zip(instruments).flatten] combines them almost the way I want, but what about turning the "guitars, vocals" string into an array first? Thanks.

Answer 1

As Rafe Kettler posted, using zip is the way to go.

Hash[members.zip(instruments)]
