Ruby. Align Output to right AND left at the same time
I have this Hash
itemHash = "124"=>["shoes", "59.99"],
"456"=>["pants", "49.50"],
"352"=>["socks", "3.99"]
I need to diplay it like this, with Description aligned to the left and Price to the right
Item Description Price
----- -------------- -----
124 shoes 59.99
352 socks 3.99
456 pants 19.50
but when I try this code
itemHash.each do |a,b|
print " #a "
b.each do |c,d|
print ("%8s %5s" % [c,d])
end
puts
end
I get this
Item Description Price
---- ----------- -----
124 shoes 59.99
456 pants 49.50
352 socks 3.99
I've tried "print ("%8s %5-s" % [c,d])" and "print ("%-8s %5s" % [c,d])" but neither does it right. For some reason when I align the description (c) it automatically applies it to the price (d). Anything I'm missing here?

Your b.each do |c,d|
loop is actually yielding each item in the array and attempting to destructure what isn't there, so you get:
"%8s %5s" % ["shoes", nil]
"%8s %5s" % ["59.55", nil]
etc.
You just need to omit your inner loop:
itemHash.each do |a,b|
print " #a "
print "%-8s %5s" % b
puts
end
Or more simply:
itemHash.each
