Ruby. Align Output to right AND left at the same time










0















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
