Ruby: What's an elegant way to pick a random line from a text file?I've seen some really beautiful examples of Ruby and I'm trying to shift my thinking to be able to produce them instead of just admire them. Here's the best I could come up with for picking a random line out of a file: def pick_random_line random_line = nil File.open("data.txt") do |file| file_lines = file.readlines() random_line = file_lines[Random.rand(0...file_lines.size())] end random_line end
