It could be Ruby; puts is more common, but there is a print. With some silly context, the answer could even be correct:

#!/usr/bin/env ruby

module DayLength
  def length
    if ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"].include? self
      "24 hours"
    else
      super
    end
  end
end

class String
  prepend DayLength
end

day = "Monday"

x = day.length

print(x)
