I\'m just giving my first steps in programming. I have just finished another class in Code Academy. This time I was asked to create a small movie catalog. Here is my questio

Answer 1

If they're simple hashes, a YAML file may be an easy way to do it.

require 'yaml'

# write hash out as a YAML file
movies = { Memento: 1, Primer: 4, Ishtar: 1 }
File.write('movies.yml', movies.to_yaml)

# read back in from file
from_file = YAML.load_file('movies.yml')

# use it
from_file[:Memento]
# => 1 
from_file[:Primer]
# => 4
