How does your script produce that output in the first place?  I'm going
to assume that you have a reference to an array and that you're printing
the output of that array's inspect method.  In that case, you could try
something like this:

array = ... # Array value from somewhere
puts array.map(&:inspect).join(", ")

This code maps each element of the array to the value of its associated
inspect method and then joins all elements of the array with ", ".  You
should be able to use similar logic if you are using something other
than the inspect method as well.
