Subject: Grade my test?


I have directory of data files along with a few other types of files.  The
data file names start at 0000 and run to 3999.  I have a program that
creates an array for the data files without the non data files.  This
program works good but have I created the shortest way of doing the task? 
Thanks for grading my test.  Jeff

#Puts the contents of the current directory into data_files.
dir_file_list = Dir.entries(".")
data_files = []

dir_file_list.each do|files| 
	if files.to_i > 0 && files.to_i < 4000
		data_files.push files
	end
end

puts data_files
