如何在 Ruby 中用 "CENSORED" 审查某些词和 return？

Question

我正在尝试从 Ruby 中的数组中删除某些词，但一直很难做到。我已经设法审查了一些词，但是当我尝试审查所有被禁止的短语时，要么标点符号丢失，要么有标点符号的词没有被审查。

test_tweets = [
  "This president sucks!",
  "I hate this Blank House!",
  "I can't believe we're living under such bad leadership. We were so foolish",
  "President Presidentname is a danger to society. I hate that he's so bad -- it sucks."
  ]
banned_phrases = ["sucks", "bad", "hate", "foolish", "danger to society"]



   censored_tweets = []

index = 0

test_tweets.each do |tweet|
  censored_tweets[index] = [] if censored_tweets[index] == nil
  tweet.split(/\W+/).each do |word|
    banned_phrases.include?(word) ? 
    censored_tweets[index].push("CENSORED") : censored_tweets[index].push(word)
  end
  censored_tweets[index] = censored_tweets[index].join(" ")
  index += 1
end

puts censored_tweets

此方法会审查所有被禁止的短语，但会删除标点符号。有人可以帮忙吗，因为这是一项无法完成的任务。

正则表达式很适合这个。正则表达式非常强大但并不总是那么容易。然而，这个很容易构建：

test_tweets = [
    "This president sucks!",
    "I hate this Blank House!",
    "I can't believe we're living under such bad leadership. We were so foolish",
    "President Presidentname is a danger to society. I hate that he's so bad -- it sucks."
    ]
 banned_phrases = ["sucks", "bad", "hate", "foolish", "danger to society"]

 regex_banned =  Regexp.union( banned_phrases) #that's all there is to it
 censored_tweets = test_tweets.map{|tweet| tweet.gsub(regex_banned, "CENSORED") }
  
 puts censored_tweets
