Question

我正在尝试显示我的打印输出，以便"|"字符输出一次，以分隔我加入的两个数组。我试图弄清楚为什么它会在每个新行上打印"|"字符。

葡萄，樱桃，李子，李子，橙，李子，樱桃，樱桃，芒果，梨| 3,0,46,3,43,28,32,34,3,34 | 14,49,48,24,12,0

"|" "14"不应该在那里。它应该继续打印数字数组。这是我的代码

我的代码

words = []
numbers = []

File.open(ARGV[0]).each_line do |line|
  mix_content = line.scan(/\w+/)

  def numeric?(lookAhead)
    lookAhead =~ /[A-Za-z]/
  end

  mix_content.each do |content|
    if numeric?(content) == 0
      words.push(content)
    else
      numbers.push(content)
    end
  end

  result = words.join(',') + '|' + numbers.join(',')
  puts result

  words.clear
  numbers.clear
  mix_content.clear

end

Answer 1

您正在一次处理一行，而某些行没有单词。像这样的一行：

3,0,46,grapes,cherry,plum,plum,3,43,28,orange,plum,cherry,cherry,32,34,3,34,mango,pear

会给：

grapes,cherry,plum,plum,orange,plum,cherry,cherry,mango,pear|3,0,46,3,43,28,32,34,3,34

但是有一句话：

14,49,48,24,12,0

没有单词，因此当您设置words.join(',')时，result为空。

Answer 2

＆＃34; |＆＃34;通过＆＃34; 14＆＃34;不应该在那里。它应该继续打印一系列数字。这是我的代码

而不是：

result = words.join(',') + '|' + numbers.join(',')

请这样做：

result = [words.join(','), numbers.join(',')].select{ |e| not e.empty? }.join('|')

或者

result = [words.join(','), numbers.join(',')].reject(&:empty?).join('|')

输出数组时打印vs put
