如何使用Ruby逐行将csv转换为数组? [英] How do I, line by line, turn a csv into an array using Ruby?

问题描述

输入文件如下:

dog,white,male
cat,purple,female
rat,gray,male

我想逐行处理该数据.

File.open("animals.csv")
  while file has next line
    currentline = array with each cell being an entry in the array
    if currentline[0] == dog
      put "dogs are cool"
    end
    put "your animal is a " + currentline[0]
  end

您明白了，对不对?我想用ifs和whatnot操纵数据行，并在最后全部打印出来.

You get the idea, right? I want to manipulate data line with ifs and whatnot and print it all out at the end.

谢谢

推荐答案

require 'csv'
CSV.foreach("animals.csv") do |row|
  puts 'dogs are cool' if row[0] == 'dog'
  puts "your animal is a #{row[0]}"
end
