A Look at Some Ruby Code, Part 2

Create a text file 'ages':

bert:    8
cookie: 11
elmo:    4
ernie:   8
zoe:     7

Then read it in:

  1: people = Array.new
  2: 
  3: File.foreach("ages") { |l|
  4:   people << Person.new($1, $2) if l =~ /(.*):\s+(\d+)/
  5: }
  6: 
  7: people 
  8:   # -> [bert (8), cookie (11), elmo (4), ernie (8), zoe (7)]
